HP Series

120 - 192 W 10:1 DC-DC Converters

Description

The converters are particularly suitable for rugged environments, such as railway applications. They have been designed in

accordance with the European railway standards EN 50155 andEN 50121-3-2. All printed circuit boards are coated with a protective

lacquer. The converter covers a total input voltage range from 12.5 to 154 VDC in the same model. The input is protected against

surges and transients occurring on the source lines. The outputs are continuously open- and short-circuit proof.

Full system ﬂexibility and n+1 redundant operating mode are possible due to series or parallel connection capabilities of the outputs

under the speciﬁed conditions. When several converters with T option are connected in parallel, a single-wire connection between

these converters ensures good current sharing. LEDs at the front panel and an isolated output OK signal indicate the status of the

converter. Voltage suppressor diodes and an independent overvoltage monitor protect the outputs against an internally generated

overvoltage.

The converters are designed using transformers with planar technology. The input voltage is fed to a booster, which generates

approximately 70 V. If V_iis higher, the booster becomes simply a diode. The resulting intermediate voltage supplies the powertrains.

There are two powertrains ﬁtted to a converter, each consisting either of a regulated single output with synchronous rectiﬁer or of a

regulated main output with a tracking second output. The output power may be ﬂexibly distributed among the main and the tracking

output of each powertrain. Close magnetic coupling in the transformers and output inductors together with circuit symmetry ensure

a small deviation between main and tracking output.

A storage capacitor charged to approx. 70 V enables the powertrains to operate during the speciﬁed interruption time.

As part of a distributed power supply system, the low-proﬁle design signiﬁcantly reduces the required volume without sacriﬁcing

high reliability. The converters are particularly suitable for 19” rack systems occupying 3 U /4 TE only, but they can also be chassis-

mounted by screws or ﬁtted with a heat sink. The connector type is H15. The fully enclosed black-coated aluminum case acts as

heat sink and RFI shield, such protecting the converter together with the coating of all components against environmental impacts.

Output Conﬁguration

The HP Series allows high ﬂexibility in output conﬁguration to cover almost every individual requirement, by simply wiring outputs

in parallel, in series, or in independent conﬁguration, as shown in the following diagrams.

Parallel or serial operation of several converters with equal output voltage is possible, using the current share option T to provide

reasonable current sharing. Choose suitable single-output models, if available.

Note: Unused tracking outputs should be connected in parallel to the respective regulated outputs.

HP Series

120 - 192 W 10:1 DC-DC Converters

Functional Description

The converters are designed using transformers with planar technology. The input voltage is fed to a booster, which generates

a voltage of approx. 70 V. If V_iis higher, the booster becomes simply a diode. The storage capacitor C_huis charged by a current

source to max. 70 V and enables the powertrains to operate during the speciﬁed interruption time. The resulting intermediate

voltage, between 45 V (during interruption time) and 154 V, supplies the powertrains.

There are two powertrains ﬁtted to a converter, each consisting either of a regulated single output with synchronous rectiﬁer or of

a regulated main output with a tracking 2^ndoutput.

As part of a distributed power supply system, the low-proﬁle design signiﬁcantly reduces the required volume without sacriﬁcing

high reliability. The converters are particularly suitable for 19” rack systems occupying 3 U /4 TE only, but they can also be chassis-

mounted by screws or ﬁtted with a heat sink. Connector type is H15. The fully enclosed Aluminum case acts as heat sink and RFI

shield, such protecting the converter together with the coating of all components against environmental impacts. The converters

are equipped with two independent forward converters, switching 180° phase-shifted to minimize the input ripple current. These

two forward converters are called “powertrains” (PT), exhibiting either a single output with synchronous rectiﬁer or two isolated

outputs, one fully regulated and the other one tracking (semi-regulated), thus providing up to four output voltages. The output

power may be ﬂexibly distributed among the main and the tracking output of a double-output powertrain. Close magnetic coupling

in the transformers and output inductors together with circuit symmetry ensure small deviation between main and tracking output.

The low input capacitance results in low and short inrush current. After the isolating transformer and rectiﬁcation, the output ﬁlter

reduces ripple and noise to a minimum without aﬀecting the dynamic response. Outputs 3 and 4, if available, are tracking (semi-

regulated). An individual current limiter built in to of each powertrain limits the total output current of that powertrain in an overload

condition. This allows ﬂexible power distribution of the outputs of each powertrain. All outputs can either be connected in series or

in parallel; see Electrical Output Data.

An auxiliary converter provides the bias voltages for the primary and secondary referenced control logic and auxiliary circuits. The

converter is only enabled, if the input voltage is within the operating voltage range and above the programmable undervoltage

lockout threshold (PUL) – such limiting the input current dependent on the nominal battery voltage.

All output are equipped with a suppressor diode and an independent monitor sensing the output voltage of the main output. In the

case of an overvoltage, it inﬂuences the control logic respectively.

The temperature is monitored and induces the converter to disable the outputs. After the temperature has dropped, the converter

automatically resumes.

Note: An internal R_PULis ﬁtted in models with option U in order to provide compatibility with the converters Series BP – EP.

Reverse polarity protection is provided by antiparallel diodes across the input, causing the external circuit breaker or fuse to trip.

A suppressor diode protects against voltage spikes beyond V_{i abs}

.

The converter is designed for an extremely wide input voltage range, allowing for connection to all common railway batteries.

However, the programmable input undervoltage lockout (PUL, pin 28) should be adjusted carefully in order to limit the input current

at start-up; see ﬁg 3.

Table 3 shows the values of the resistor R_PUL, connected between PUL and Vi–, versus the resultant minimum input voltage and

the resultant maximum input current. Fig. 4 shows more values of R_PULversus start-up voltage. For stationary batteries, a higher

start-up voltage might be advantageous.

Note: If PUL (pin 28) is connected to Vi– (pin 32), the converter is disabled. See also Inhibit Function.

Inrush Current

The converters exhibit small input capacitance C_i. However, a short peak current appears when applying the input voltage.

Note: The storage capacitor C_huis charged by a current source and does not contribute to the inrush current.

The peak inrush current can be found by following calculation; see also ﬁg. 5:

HP Series

120 - 192 W 10:1 DC-DC Converters

Actually, a HP Series converter with its load acts as negative resistor r_i, because the input current I_irises, when the input voltage V_i

decreases. It tends to oscillate with a resonant frequency determined by the line inductance L_extand the input capacitance C_ext+ C_i

damped by the resistor R_ext. The whole system is not linear at all and eludes a simple calculation. One basic condition is given by

the formula:

R_extis the series resistor of the voltage source including supply lines. If said condition is not fulﬁlled, the converter may not reach

stable operating conditions. Worst case conditions are lowest V_iand highest output power P_o.

Low inductance L_extof the supply lines and an additional capacitor C_extare helpful. Recommended values for C_extare given in table 4,

which should allow for stable operation up to an input inductance of 2 mH. C_iis speciﬁed in table 2.

HP Series

120 - 192 W 10:1 DC-DC Converters

Parallel and Series Operation

The ﬁrst outputs of power trains with equal nominal output voltage can be connected in parallel. Where available, we recommend

ordering of option T.

Any output can be connected in series with any other output. If the main and the tracking output of the same power train are

connected in series, consider that the eﬀect of the R-input is doubled.

Notes:

•

If a tracking output is not used, connect it in parallel to the respective regulated main output.

Connection of several outputs in parallel should include measures to approximate all output currents. Single-output power trains exhibit

current-share pins (T), which must be interconnected. If no current-share pins are available, the load lines should exhibit a similar resistance.

•

The PUL-pins (pin 28) should exhibit an individual PUL resistor for each converter. If the shutdown function is used, each PUL-pin must

be controlled individually.

If several outputs are connected in series, the resulting voltage may exceed the SELV level (SELV = Safety Extra Low Voltage) and require

additional safety measures in order to comply with international safety standards.

Parallel operation of two double-output converters with series-connected outputs is shown in ﬁg. 9. The link between the T pins

ensures proper current sharing, even though only the ﬁrst outputs are inﬂuenced by T-function. Sense lines are connected directly

at the connector, and load lines have equal length and section.

Redundant Systems

An example of a redundant system using converters with 2 regulated outputs (HP2020) is shown in ﬁg. 10. Load 1 is powered with

5.1 V and load 2 with 12 V.

The converters are separated with ORing diodes. If one converter fails, the remaining one still delivers the power to the loads.

If more power is needed, the system may be extended to more parallel converters (n+1 redundancy).

Current sharing of the 5.1 V outputs is ensured by the interconnected T pins, whereas the sense lines are connected after the

ORing diodes to maintain the correct output voltage.

For the 12 V outputs, no active current-share feature is available. As a result, 2 little diodes D_s(loaded by small resistors R_s)

simulate the voltage drop of the ORing diodes. Reasonable current sharing is provided by load lines of equal length and section.

Output Voltage Regulation

Line and load regulation of the regulated outputs is so good that input voltage and output current have virtually no inﬂuence to the

output voltage.

If a tracking output is not loaded, its output voltage may rise considerably. Thus, unused tracking outputs should be connected in

parallel to the respective main output.

The dynamic load regulation is shown in ﬁg. 11.

Typical dynamic load regulation of the output voltage

Tracking Outputs

The main outputs 1 and 2 are regulated to V_{o nom}independent of the output current. If the loads on outputs 3 and 4 are too low

(<10% of I_{o nom}), their output voltage tends to rise. V_o3and V_o4depend on the load distribution: If all outputs are loaded with at least

10% of I_{o nom}, V_o3and V_o4remain within ±5% of V_{o nom}. The chart ﬁg. 12 shows the regulation of the tracking outputs under diﬀerent

load conditions. If I_o1= I_o4and I_o2= I_o3or if the tracking outputs are connected in series with their respective regulated outputs,

then V_o3and V_o4remain within ±1% of V_{o nom}, provided that the load is at least I_{o min}

.

Because the HP Series uses main transformers in planar technology, the tracking outputs follow the main outputs very closely.

Note: If a tracking output (V_o3or V_o4) is not loaded, it should be connected in parallel to the respective main output

(V_o3parallel to V_o2, V_o4parallel to V_o1).

HP Series

120 - 192 W 10:1 DC-DC Converters

Output Current Protection

All outputs are continuously protected against open-circuit (no load) and short-circuit by an electronic current limitation.

Single- and double-output powertrains have a rectangular current limitation characteristic. In double output power-trains, only

the total current is limited allowing free choice of load distribution between the two outputs of each power train up to a total

I_o1+ I_o4= I_{o max}or I_o2+ I_o3= I_{o max}

.

All outputs are protected by an individual suppressor diode. In addition, the main outputs are monitored. In the case of an

overvoltage (caused by a defect), the monitoring circuit resets the PWM logic and the output voltage.

Interruption Time

The interruption time t_hu(ride-through time) of the system complies to class S2 (≥10 ms) according to EN 50155:2017, clause

5.1.1.4. It is valid for interruption and a short-circuit of the input voltage V_i(V_i≥ 24 V).

After such an event, the system is ready for the next event after 10 s.

Note: t_huis the minimum interruption time, but depending on diﬀerent operating conditions, this time can be much longer.

Thermal Considerations and Protection

If a converter is mounted upright in free air allowing for unrestricted convection cooling and is operated at nominal input voltage

(24 V to 110 V) and nominal output power at T_{A max}(see table Temperature speciﬁcations), the temperature T_Cmeasured at the

measurement point on the case (see Mechanical Data) approaches T_{C max}after an initial warm-up phase. However the relationship

between T_Aand T_Cdepends heavily on the operating conditions and system integration. The thermal conditions are inﬂuenced

signiﬁcantly by the input voltage, the output current, airﬂow, and the temperature of the adjacent elements and surfaces. T_{A max}is

therefore in contrast to T_{C max}an indicative value only.

Operating the converters with output currents beyond I_{o nom}requires a reduction of the maximum ambient temperature or forced-air

cooling in order to keep T_Cbelow 100 °C. When T_{C max}is exceeded, the thermal protection (sensors near the output rectiﬁers of

each powertrain) is activated and disables the outputs. The converter automatically resumes when the temperature drops.

At T_A≤ 71 °C, P_{o nom}is continuously possible, if V_i≥ 16.8 V.

At T_A≤ 50 °C, P_{o 50}is continuously possible, if V_i≥ 22 V.

Note: Forced cooling or an additional heat sink (option B, B1, B3) improves the reliability or allow T_Afor going beyond T_{A max}provided that T_{C max}

is not exceeded. In rack systems without proper thermal management the converters must not be packed too closely together! In such a case

the use of 5 or 6 TE front panels is recommended.

Circuit for the inhibit function (not with options U, V)

Typical output response to the PUL-signal (used as inhibit)

or to the inhibit signal with option U or V

The current coming out from pin 28 (PUL) is typ. 0.6 mA (<1 mA). If pin 28 is left open-circuit, the voltage is 5 V. The converter is

disabled when V_PULis ≤ 0.7 V.

Note: For converters with opt. U or V, see Primary Inhibit for Option U and V (page 26).

Current Share Function

If the T-pins of parallel-connected single-output powertrains are linked together, the powertrains share their output current evenly.

Refer to section Parallel and Series Connection.

Output Voltage Adjust of V_o1and V_o4

Note: With open R-input, V_o= V_{o nom}

.

The converters allow for adjusting the output voltage of powertrain 1. Powertrain 2 cannot be adjusted, except for single-output

converters. Programming is performed by an external resistor R_ext1or R_ext2, connected to the R-input. The adjust range is limited

to the values given in table Electrical Output Data.

With double-output powertrains, both outputs V_o1and V_o4are inﬂuenced by the R-input setting simultaneously.

Adjustment of V_o(or V_o1) is possible by means of an external resistor R_ext. V_o4is tracking the voltage V_o1. The trim range of V_o(or V_o1)

is speciﬁed in table 5 as V_{o tr}.

Depending on the value of the required output voltage, the resistor shall be connected:

either: Between the R-pin and S– (or Vo1–) to adjust the output voltage to a value below V_{o nom}

:

V_o

__________

R_ext1≈ 4 kΩ •

V_{o nom}– V_o

or: Between the R-pin and S+ (or Vo1+) to adjust the output voltage to a value greater than V_{o nom}

:

(V_o– 2.5 V)

_________________

R_ext2≈ 4 kΩ •

2.5 V • (V_o/V_{o nom}– 1)

Note: Adjustment by an external voltage source is not recommended.

Sense Lines

Important: Sense lines should always be connected. Incorrectly connected sense lines may damage the converter. If sense pins are left open-

circuit, the output voltages are not accurate.

This feature enables compensation of voltage drop across the connector contacts and the load lines including ORing diodes in

true redundant systems.

Applying generously dimensioned cross-section load leads avoids troublesome voltage drop. To minimize noise pick-up, wire

sense lines parallel or twisted to the respective output line. To be sure, connect the sense lines directly at the female connector.

The voltage diﬀerence between any sense line and its respective power output pin (as measured on the connector) should not

exceed the following values at nominal output voltage.

LEDs and Out OK Monitor

When the input voltage is in range, the green LED “In OK” is shining provided that the inhibit function is not activated.

The voltage(s) of the main output(s) are monitored. When the main outputs are in range, the LED “Out OK 1” and “Out OK 2”

are activated.

In addition a galvanically isolated open-collector signal “Out OK” is generated. This function is not adjustable, but if the R-input is

used to adjust V_o, the trigger levels are tracking.

The open collector output is conducting, if the monitored conditions are fulﬁlled (tolerances typ. ±3%). Otherwise, the input voltage

is out of limits or the output current is too high.

Electromagnetic Emissions

All conducted emissions (fig. 20) have been tested according to EN 55011, group 1, class A. These limits are much stronger than

requested in EN 50121-3-2:2016, table 2.1, and coincide with EN 50121-4:2016, table 1.1. The limits in ﬁg. 20 apply to quasipeak

values, which are always lower then peak values.

In addition, the values for average must keep a limit 10 dBµV below the limits in ﬁg. 20 (not shown).

Radiated emissions have been tested according to EN 55011, group 1, class A . These limits are similar to the requirements

of EN 50121-3-2:2016 and EN 50121-4:2016, both calling up EN 61000-6-4+A1:2011, table 1. The tests were executed with

HP Series

120 - 192 W 10:1 DC-DC Converters

Installation Instructions

These converters are components, intended exclusively for inclusion within other equipment by an industrial assembly process or

by a professionally competent person. Installation must strictly follow the national safety regulations in respect of the enclosure,

mounting, creepage distances, clearances, markings and segregation requirements of the end-use application.

Connection to the system shall be made via the female connector H15 (see Accessories). Other installation methods may not meet

the safety requirements. Check for hazardous voltages before altering any connections. Pin 26 (PE) is a leading pin and is reliably

connected to the case. For safety reasons it is essential to connect this pin to the protective earth.

No fuse is incorporated in the converter. An external circuit breaker or a fuse in the wiring to one or both input pins (no. 30 and/

or no. 32) are necessary to ensure compliance with local requirements.

Do not open the converters, or the warranty will be invalidated. Make sure that there is suﬃcient airﬂow available for convection cooling.

This should be veriﬁed by measuring the case temperature at the speciﬁed measuring point, when the converter is operated in the

end-use application. T_{C max}should not be exceeded. Ensure that a failure of the converter does not result in a hazardous condition.

Standards and Approvals

The HP Series converters are safety-approved according to the latest edition of IEC/EN60950-1 and UL/CSA60950-1.

They have been evaluated for:

• Class I equipment

• Building in

• Double or reinforced insulation based on 250 VAC or 240 VDC between input and output and between input and auxiliary circuits

• Overvoltage category II

• Pollution degree 2 environment

• The converters fulﬁll the requirements of a ﬁre enclosure.

The converters are subject to manufacturing surveillance in accordance with the above mentioned ULstandards and with ISO 9001:2015.

Cleaning Liquids and Protection Degree

The converters are not hermetically sealed. In order to avoid possible damage, any penetration of liquids shall be avoided.

The converters correspond to protection degree IP 40, provided that the female connector is ﬁtted to the converter.

Railway Applications

The HP Series converters have been designed observing the railway standards EN 50155:2017 and EN 50121-3-2:2016.

All boards are coated with a protective lacquer.

The converters fulﬁl the requirements of the ﬁre safety standard EN 45545-2, hazard levels HL1 to HL3.

Isolation

The electric strength test is performed in the factory as routine test in accordance with EN 50514 and IEC/EN 60950 and should

not be repeated in the ﬁeld. The Company will not honor warranty claims resulting from incorrectly executed electric strength tests.

120 - 192 W 10:1 DC-DC Converters

Description of Options

Option T: Active Current Sharing

For single-output powertrains only. The current-share function should be used, when several powertrains are operated in parallel.

Examples could be high reliability n+1 redundant systems or systems providing higher output power.

Using this feature reduces the stress of individual converters and improves the reliability of the system. Interconnection of the current-

sharing pins T causes the converters to share their output currents evenly.

In redundant systems, the outputs of the converters have to be decoupled by ORing diodes. Consequently, a failure of one converter

will not lead to a system failure.

To ensure correct operation of the current-share function, the installer must ensure that the S– pins of all parallel converters are at the

same electrical potential and that there are no voltage drops across the connecting lines between these pins.

Double-output converters with outputs connected in series can also be paralleled with current sharing, if pins Vo1– of all converters

are connected together; see ﬁg. 9.

If the output voltages of parallel connected single-output converters are programmed to a voltage other than V_{o nom}by means of the

R-pin, the outputs should be adjusted individually within a tolerance of ±1%.

Note: The T-function inﬂuences V_o1only.

Option U: Preadjusted Undervoltage Lockout UVL

For compatibility with former P Series converters, the start-up and the shutdown voltage are preadjusted depending on the nominal

battery voltage. In addition, pin 28 (i) is used as inhibit; refer to the clause Primary Inhibit below.

Table 14 deﬁnes the start-up and shutdown voltages. For the recommended fuses, refer to table 3.

Option V: Rotary Switch to Adjust UVL

Converters with option V allow for adjustment of the shutdown voltage by means of a 4 position rotary switch, accessible through

a hole in the case. In addition, pin 28 (i) is used as inhibit; refer to the clause Primary Inhibit below.

Table 14 deﬁnes the start-up and shutdown voltages. For the recommended fuses, refer to table 3. The rotary switch is set in the

factory to position D.

Primary Inhibit for Option U and V

This inhibit (pin 28) input enables (logic low) or disables (logic high or open-circuit) the output. In systems consisting of several

converters, this feature may be used to control the activation sequence by logic signals or to enable the power source to start up,

before full load is applied.

The output response is shown in ﬁg. 14.

Note: If this function is not used, pin 28 must be connected with pin 32, otherwise the internal logic will disable the output.
