Description

panel allow for a check of the main output voltage.

Full system flexibility and n+1 redundant operating mode are

possible due to virtually unrestricted series or parallel

connection capabilities of all outputs. In parallel connection of

several converters, automatic current sharing is provided by a

single-wire interconnection.

These extremely compact DC-DC converters incorporate all

necessary input and output filters, signaling and protection

features, which are required in the majority of applications.

The converters provide important advantages such as flexible

output power through primary current limitation, high

efficiency, excellent reliability, very low ripple and RFI noise

levels, full input to output isolation, negligible inrush current,

overtemperature protection, and input over-/undervoltage

lockout. The converter inputs are protected against surges

and transients occurring on the source lines.

As a modular power supply or as part of a distributed power

supply system, the extremely low profile design significantly

reduces the necessary power supply volume without

sacrificing high reliability. A temperature sensor disables the

outputs, if the case temperature exceeds the limit. The outputs

are automatically re-enabled, when the temperature drops

below the limit.

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 and EN 50121-3-2. All printed circuit boards are

coated with a protective lacquer.

The fully enclosed, black-coated aluminum case acts as a heat

sink and an RFI shield. The converters are designed for 19"

DIN-rack systems occupying 3 U/4 TE only, but can also be

chassis-mounted by means of four screws. Fitting an

additional heat or ordering options with fitted heat sink is

possible as well.

The outputs are continuously open- and short-circuit proof. An

isolated output Power Good signal and LEDs at the front panel

indicate the status of the converter. Test sockets at the front

The current limitation is located at the primary side, thus

limiting the total output current in overload conditions. This

allows flexible loading of each output for unsymmetrical loads

in the range 10 to 90% of the total output power. In applications

with large dynamic load changes, we recommend connecting

such a load to output 1. If output 2 is not used, it should be

connected parallel to output 1. Both outputs can either be

series- or parallel-connected (see Electrical Output Data).

Functional Description

The converters are designed as forward converters using

primary and secondary control circuits in SMD technology. The

switching frequency is approximately 200 kHz under nominal

operating conditions. The built-in high-efficient input filter

together with a small input capacitance generate very low

inrush currents of short duration. After transformer isolation

and rectification, the output filter reduces ripple and noise to a

minimum without compromising the dynamic ability. The

output voltage is fed to the secondary control circuit via

separate sense lines. The resultant error signal is sent to the

primary control circuit via a signal transformer.

In normal operation, the internal control circuits are powered

by a third winding of the main choke (except 48Q models).

Start-up is ensured from the input voltage by a linear regulator.

Note: When the output voltage is much lower then the nominal

value, this linear regulator is activated, generating considerable

power losses.

Double-output models have the voltage regulation of output 2

relying on the close magnetic coupling of the transformer and

the output inductor together with the circuits' symmetry.

Input Fuse

Input Stability with Long Supply Lines

An incorporated fuse in series to the negative input line

protects against severe defects. The fuse is not externally

accessible. Reverse polarity at the input will cause the fuse to

blow.

If a Q Series converter is connected to the power source with

long input lines which exhibit a considerable inductance, an

additional external capacitor connected in parallel to the input

improves stability and avoids oscillations.

Note: Customer-specific models with no internal fuse are

available on request; the customer must prevew an external fuse

according to table 3.

Actually, a Q Series converter with nominal load acts like a

negative resistor, as the input current rises when the input

voltage decreases. It tends to oscillate with a resonant

frequency determined by the line inductance L_extand the input

The whole system is not linear at all and eludes a simple

calculation. One basic condition is given by the formula:

Low inductance L_extof the input lines and a parallel connected

input capacitor C_extare helpful. Recommended values for C_ext

are given in table 4, which should allow stable operation up to

an input inductance of 2 mH.

Input Transient Protection

A metal oxide VDR (Voltage Dependent Resistor) together with

the input fuse and a symmetrical input filter form an effective

protection against high input transient voltages, which typically

occur in most installations, especially in battery-driven mobile

applications.

Nominal battery voltages in use are: 24, 36, 48, 60, 72, 96, and

In some applications, surges according to RIA 12 are specified

in addition to those defined in IEC 60571-1 or EN 50155. The

power supply must not switch off during these surges and

since their energy can practically not be absorbed, an

extremely wide input voltage range is required. The Q Series

input range has been designed and tested to meet most of

these requirements. See also Electromagnetic Immunity.

The inherent inrush current value is lower than specified in the

standard ETS 300132-2. The converters operate with

relatively small input capacitance, resulting in low inrush

current of short duration. As a result, in a power-bus system

the converters can be hot-swapped, causing negligible

disturbance.

Redundant Configuration

Fig. 10a shows a circuit with ORing diodes D_Rin the positive

output lines, forming a redundant configuration. For accurate

output voltage regulation, the sense lines are connected after

the ORing diodes. The T pins should be connected together to

If one of the converters fails, the remaining converters can

deliver the whole output power.

Note: The current-share logic can only increase the output voltage

marginally and remains functional even in the case of a failing

converter.

D_R

Fig. 10b shows a quite similar circuit with ORing diodes D_R, but

with different output loads. To compensate for the voltage drop

of the ORing diodes (if necessary), an auxiliary circuit is added

to each power supply consisting of a small diode D_Sand a

small resistor R_S. We recommend a current of approximately 10

mA through D_Sand R_S. Only Load 0 benefits from a secured

supply voltage.

The current sharing may be improved by interconnecting the T

more flexible and less sensitive.

Caution: Do not connect the sense lines after the ORing diodes,

but directly with the respective outputs. If for some reason one of

the converters switches off and the ORing diode is blocking, a

reverse voltage can appear between the sense pin and the

respective output pin and damage the converter.

In a symmetrical configuration the output 1 with open R input is

regulated to V_{o1 nom}, regardless of the output currents. If the

load on output 2 is too small (<10% of I_{o nom}), its voltage will

rise and may activate the overvoltage protection, which will

then reduce the voltage on both outputs.

different load distributions up to the current limit. If I_o1= I_o2or

the two outputs are connected in series, the deviation of V_o2

Double-output models with 12 V: Voltage deviation of V_o2

versus I_o2for different currents on output 1

In double-output models, only the total current is limited,

allowing free choice of load distribution between the two

outputs, up to I_o1+ I_o2≤ I_{o max}. However, a small current should

remain on both outputs to guarantee good voltage regulation.

In case of overload (I_o1+ I_o2> I_{o max}) both output voltages are

reduced simultaneously.

Current distribution in overload is dependent upon the type of

overload. A short-circuit in one output will cause the full current

flow into that output, whereas a resistive overload results in

more even distribution and in a reduced output voltage.

If a converter is located upright in quasi-stationary air

is operated at its nominal input voltage and output power, the

temperature T_Cmeasured at the Measuring point of case

temperature (see Mechanical Data) will approach T_{C max}after

* Models with version V104 or higher

Note: T-function only increases the output voltage, until the

currents are evenly shared. If in a redundant system, one

converter fails, the remaining converters keep sharing their

currents evenly.

Current Sharing

The current sharing facility should be used when several

converters are operated in parallel or redundant connection.

This feature avoids that some converters are driven into

current limitation and thus produce excessive losses. As a

result, the stress of the converters is reduced, and the system

reliability is further improved.

Since the T pins are referenced to the pins S–, the S– pins of

all converters must have the same electrical potential.

Double-output converters with both outputs connected in

series can also be paralleled with current sharing, if pins Vo1–

of all converters are connected together, see fig. 8c.

Simple interconnection of the T pins causes the converters to

share the output current. The current tolerance of each

converter is approx. ±20% of the sum of its nominal output

If the output voltages are programmed to a voltage other than

V_{o nom}by means of the R pin or option P, the outputs should be

adjusted individually within a tolerance of ±1%.

currents I_{o1 nom}+ I_{o2 nom}

.

In n+1 redundant systems, a failure of a single converter will

not lead to a system failure, if the outputs are decoupled by

diodes; see fig. 10.

Important: For applications using the hot-swap capabilities,

dynamic output voltage changes during plug-in/plug-out must be

considered.

Q Series Data Sheet

66 – 132 Watt DC-DC Converters

®

Applying generously dimensioned cross-section load leads

help avoiding troublesome voltage drops. To minimize noise

pick-up, wire the sense lines parallel or twisted. For

unsymmetrical loads, we recommend connecting the sense

lines directly at the female connector.

Output Good Signal (Out-OK)

The isolated Out-OK output gives a status indication of the

converter and the output voltage. It can be used for control

functions such as data protection, central system monitoring or

as a part of a self-testing system. It can be connected to get a

centralized fault detection or may be used for other system-

specific applications at the primary or the secondary side of

the converter.

To ensure correct operation, both sense lines must be

connected to their respective power output. With double-

output models, the sense lines must be connected to output 1

only. Caution should be exercised, if outputs are series-

connected, as the compensated voltage is effectively doubled.

Because the effective output voltage and output power are

increased by the sense lines, the minimum input voltage rises

proportionally to the compensated output voltage.

Connecting the Out-OK as per fig. 22, V_OK<1.0 V indicates that

the V_oor V_o1of the converter is within the range V_{t1 low}– V_{t1 high}

V_{t1 low}corresponds to 0.95 - 0.98 V_{o1 nom}, V_{t1 high}to 1.02 – 1.05

V_{o1 nom}

.

Note: Using the R-input or the option P, the monitor level is

tracking the programmed output voltage.

Caution: Sense lines should always be connected. Incorrectly

connected sense lines may cause an overvoltage at the ouput,

which could damage the output load and activate the second

control loop. The sense lines can handle only small currents.

In an error condition, if the output voltage is out of range due to

overload or an external overvoltage, V_OKwill approach V_p.

The output is formed by an NPN transistor. The emitter (Out

OK–) can be connected to primary Vi– or secondary Vo1– to

get an open-collector output. In a configuration of several Q

Series converters, the Out OK pins can be series-connected in

order to get a system level signal (as shown in fig. 9). If one of

the converters fails, the series-connected output rises to high

impedance.

The Vi– input (pin 32) is internally fused. This fuse is designed

to protect in case of overcurrent and may not be able to satisfy

all customer requirements. External fuses in the wiring to one

or both input pins (no. 30 and/or no. 32) may therefore be

necessary to ensure compliance with local requirements.

Safety and Installation Instructions

Connector Pin Allocation

The connector pin allocation table defines the electrical

potentials and the physical pin positions on the H15 connector.

Pin no. 26, the protective earth pin, is a leading pin, ensuring

that it makes contact with the female connector first.

Important:

• If the inhibit function is not used, pin 28 (i) must be connected

with pin 32 (Vi–) to enable the output(s).

Table 18: Pin allocation of the H15 connector

Due to high output currents, the Q1001/1101 models offer two

internally parallel-connected contacts for both, the positive and

the negative output path (pins 4/6 and pins 8/10). It is

recommended to connect the load to both female connector

pins of each path in order to keep the voltage drop across the

connector pins to a minimum.

Installation Instructions

The

Q

Series converters are components, intended

The converters have been evaluated for:

• Class I equipment

exclusively for inclusion within other equipment by an

industrial assembly operation or by professional installers.

Installation must strictly follow the national safety regulations

in compliance to enclosure, mounting, creepage, clearance,

casualty, markings and segregation requirements of the end-

use application.

• Building in

• Basic insulation between input and case and double or

reinforced insulation between input and output, based on

their maximum rated input voltage

Connection to the system shall be made via the female

connector H15 (see Accessories). Other installation methods

may not meet the safety requirements.

• Basic insulation between Out-OK and case, and double or

reinforced insulation between Out-OK and input, and

between Out-OK and output, based on their maximum rated

input voltage

The Q Series converters are provided with pin 26 ( ), which is

reliably connected to the case. For safety reasons it is

essential to connect this pin to protective earth; see Safety of

Operator-Accessible Output Circuits.

• Functional insulation between outputs and output to case

• Use in a pollution degree 2 environment

The converters are subject to manufacturing surveillance in

accordance with the above mentioned standards and with ISO

9001:2000.

Safety of Operator-Accessible Output Circuits

If the output circuit of a DC-DC converter is operator-

accessible, it shall be an SELV circuit according to IEC 60950.

Railway Applications

The Q Series converters have been designed by observing the

railway standards EN 50155, EN 50121-3-2, and EN 50121-4.

All boards are coated with a protective lacquer.

Table 21 shows some possible installation configurations,

compliance with which causes the output circuit of the DC-DC

converter to be SELV up to a configured output voltage (sum of

nominal voltages, if in series configuration) of 35 V.

The converters comply with class S1 of the fire protection

standard E DIN 5510-2 (Oct. 2007).

However, it is the sole responsibility of the installer to ensure

the compliance with the relevant and applicable safety

regulations.

Isolation and Protective Earth

The test of the resistance of the protective earthing circuit

reduced accordingly, so that the maximum specified output

power is not exceeded.

Description of Options

Option P: Output Voltage Adjustment

Option -7: Temperature Range

Option P provides a built-in multi-turn potentiometer, which

allows an output voltage adjustment of ±10% of V_{o nom}. The

potentiometer is accessible through a hole in the front cover.

Option -7 designates converters with an operational ambient

temperature range of –25 to 71 °C. Not for new designs.

With double-output models, both outputs are affected by the

potentiometer. If converters are parallel-connected, their in-

dividual output voltage should be set within a tolerance of ±1%.

Option B, B1: Additional Heat Sink

Thickness: 12.5 mm (opt. B) or 20 mm (opt. B1)

If V_ois set higher than V_{o nom}, the output currents should be

The maximum rated input voltage of EQ models acc. to IEC/EN 60950 is 150 V. Power-One specifies the tolerance as +12% (max. 168 V)

The earth connection has to be provided by the installer according to IEC/EN 60950.

Based on the maximum rated output voltage provided by the front end.

The installer shall provide an approved fuse with the lowest rating suitable for the application in a non-earthed input conductor directly at

the input of the DC-DC converter (see fig. Schematic safety concept). For UL’s purposes, the fuse needs to be UL-listed.

Each suppressor diode should be dimensioned such that in the case of an insulation fault the diode is able to limit the output voltage to

SELV (<60 V), until the input fuse blows (see fig. Schematic safety concept).

Has to be insulated from earth according to IEC/EN 60950, by at least supplementary insulation, based on the maximum nominal output

voltage from the front end.
