K Series

150 W DC-DC and AC-DC Converters

Description

The K Series of DC-DC and AC-DC converters represents a broad and ﬂexible range of power supplies for use in advanced

electronic systems. Features include high eﬃciency, high reliability, low output voltage noise and excellent dynamic response to

load/line changes. LK models can be powered by DC or AC with a wide-input frequency range (without PFC).

The converter inputs are protected against surges and transients. An input over- and undervoltage lockout circuitry disables the

outputs, if the input voltage is outside of the speciﬁed range. Certain types include an inrush current limiter preventing circuit

breakers and fuses from tripping at switch-on.

All outputs are open- and short-circuit proof, and are protected against overvoltages by means of built-in suppressor diodes. The

output can be inhibited by a logic signal applied to pin 18 (i). The inhibit function is not used, pin 18 must be connected with pin

14 to enable the outputs.

LED indicators display the status of the converter and allow for visual monitoring of the system at any time.

Full input-to-output, input-to-case, output-to-case, and output to output isolation is provided. The converters are designed, built,

and safety-approved to the international safety standards IEC/EN 60950-1. They are particulary suitable for railway applications

and comply with EN 50155 and EN 50121-3-2.

The case design allows operation at nominal load up to 71 °C with natural cooling. If forced cooling is provided, the ambient

temperature may exceed 71 °C, but the case temperature must remain below 95 °C.

A temperature sensor generates an inhibit signal, which disables the outputs when the case temperature T_Cexceeds the limit. The

outputs are automatically re-enabled, when the temperature drops below the limit.

Various options are available to adapt the converters to individual applications.

The converters may either be plugged into a 19” DIN-rack system according to IEC 60297-3, or be chassis mounted.

Important: For applications requiring compliance with IEC/EN 61000-3-2 (harmonic distortion), please use our LK4000 or LK5000

Series with incorporated power factor correction (PFC).

K Series

150 W DC-DC and AC-DC Converters

Functional Description

The input voltage is fed via an input fuse, an input ﬁlter, a bridge rectiﬁer (LK models only), and an inrush current limiter to the

input capacitor. This capacitor sources a single-transistor forward converter with a special clamping circuit and provides also the

power during the hold-up time.

Each output is powered by a separate secondary winding of the main transformer. The resultant voltages are rectiﬁed and their

ripple smoothed by a power choke and an output ﬁlter. The control logic senses the main output voltage V_o1and generates, with

respect to the maximum admissible output currents, the control signal for the switching transistor of the forward converter.

The second output of double-output models is tracking the main output, but has its own current limiting circuit. If the main output

voltage drops due to current limitation, the second output voltage will fall as well and vice versa.

Standard models with a single 5.1 V output have a synchronous rectiﬁer to provide good eﬃciency.

150 W DC-DC and AC-DC Converters

Input Transient Protection

A suppressor diode or a VDR (depending upon the input voltage range) 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, but especially

in battery-driven mobile applications.

Standard nominal battery voltages are: 12, 24, 36, 48, 60, 72, 110, and 220 V. Railway batteries are speciﬁed with a tolerance of

–30% to +25%, with short excursions up to ±40%.

In certain applications, additional surges according to RIA12 are speciﬁed. The power supply must not switch oﬀ during these

surges, and since their energy can practically not be absorbed, an extremely wide input range is required. The EK input range for

110 V batteries has been designed and tested to meet this requirement.

Input Fuse

A fuse mounted inside the converter protects against severe defects. This fuse may not fully protect the converter, when the input

voltage exceeds 200 VDC. In applications, where the converters operate at source voltages above 200VDC, an external fuse or

a circuit breaker at system level should be installed.

Inrush Current Limitation

The CK, DK, EK, and LK models incorporate an NTC resistor in the input circuitry, which at initial turn-on reduces the peak inrush

current value by a factor of 5 – 10, such protecting connectors and switching devices from damage. Subsequent switch-on cycles within

short periods will cause an increase of the peak inrush current value due to the warming-up of the NTC resistor. See also Option E.

The inrush current peak value (initial switch-on cycle) can be determined by following calculation; see also ﬁg. 3:

Reverse Polarity

The converters (except LK models) are not protected against reverse polarity at the input to avoid unwanted power losses.

In general, only the input fuse will trip.

LK models are fully protected by the built-in bridge rectiﬁer.

Input Under-/Overvoltage Lockout

If the input voltage remains below approx. 0.8 V_{i min}or exceeds approx. 1.1 V_{i max}, an internally generated inhibit signal disables

the output(s). When checking this function, the absolute maximum input voltage V_{i abs}should be observed. Between V_{i min}and the

undervoltage lock-out level the output voltage may be below the value deﬁned in table Electrical Output data.

Thermal Considerations

If a converter is located in free, quasi-stationary air (convection cooling) at the indicated maximum ambient temperature T_{A max}(see

table Temperature speciﬁcations) and is operated at its nominal input voltage and output power, the temperature measured at the

Measuring point of case temperature T_C(see Mechanical Data) will approach the indicated value T_{C max}after the warm-up phase.

However, the relationship between T_Aand T_Cdepends heavily upon the conditions of operation and integration into a system.

The thermal conditions are inﬂuenced by input voltage, output current, airﬂow, and temperature of surrounding components and

surfaces. T_{A max}is therefore, contrary to T_{C max}, an indicative value only.

Caution: The installer must ensure that under all operating conditions T_Cremains within the limits stated in the table Temperature speciﬁcations.

Notes: Suﬃcient forced cooling or an additional heat sink allows T_Ato be higher than 71 °C (e.g., 85 °C), as long as T_{C max}is not exceeded.

Details are speciﬁed in ﬁg. 8.

Output current derating versus temperature for -7 and -9 models.

Thermal Protection

A temperature sensor generates an internal inhibit signal, which disables the outputs, when the case temperature exceeds T_{C max}

.

The outputs automatically recover, when the temperature drops below this limit.

Continuous operation under simultaneous extreme worst-case conditions of the following three parameters should be avoided:

Minimum input voltage, maximum output power, and maximum temperature.

Output Protection

Each output is protected against overvoltages, which could occur due to a failure of the internal control circuit. Voltage suppressor

diodes (which under worst case condition may become a short circuit) provide the required protection. The suppressor diodes are

not designed to withstand externally applied overvoltages. Overload at any of the outputs will cause a shut-down of all outputs.

A red LED indicates the overload condition.

Note: V_{o BR}is speciﬁed in Electrical Output Data. If this voltage is exceeded, the suppressor diode generates losses and may become a short circuit.

Parallel and Series Connection

Single- or double-output models with equal output voltage can be connected in parallel using option T (current sharing). If the T pins

are interconnected, all converters share the output current equally.

Single-output models and/or main and second outputs of double-output models can be connected in series with any other (similar) output.

Notes:

– Parallel connection of double-output models should always include both, main and second output to maintain good regulation.

– Not more than 5 converters should be connected in parallel.

– Series connection of second outputs without involving their main outputs should be avoided, as regulation may be poor.

– The maximum output current is limited by the output with the lowest current limitation when several outputs are connected in series.

Output Voltage Regulation

Figure 10 applies to single-output or double-output models with parallel-connected outputs.

For independent conﬁguration, output 1 is under normal conditions regulated to V_{o nom}, irrespective of the output currents.

V_o2depends upon the load distribution. If both outputs are loaded with more than 10% of I_{o nom}, the deviation of V_o2remains within

±5% of V_o1. Figures 11 to 13 show the regulation depending on load distribution.

Two outputs of a double-output model connected in parallel behave like the output of a single-output model.

Note: If output 2 is not used, connect it in parallel with output 1! This ensures good regulation and eﬃciency.

Inhibit for Remote On/Oﬀ

The outputs may be enabled or disabled by means of a logic signal (TTL, CMOS, etc.) applied between the inhibit input i (pin 18)

and pin 14 (S– or Vo1–). In systems with several converters, this feature can be used to control the activation sequence of the

converters. If the inhibit function is not required, connect the inhibit pin 18 with pin 14!

Sense Lines (Single Output Models)

Important: Sense lines must always be connected! Incorrectly connected sense lines may activate the overvoltage protection resulting in a

permanent short-circuit of the output.

This feature allows for compensation of voltage drops across the connector contacts and if necessary, across the load lines. We

recommend connecting the sense lines directly at the female connector.

To ensure correct operation, both sense lines (S+, S–) should be connected to their respective power outputs (Vo+ and Vo–), and

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

the following values:

As a standard feature, the converters oﬀer an adjustable output voltage, identiﬁed by letter R in the type designation. The control

input R (pin 16) accepts either a control voltage V_extor a resistor R_extto adjust the desired output voltage. When input R is not

.

a) Adjustment by means of an external control voltage V_extbetween pin 16 (R) and pin 14 (S–):

Warnings:

– V_extshall never exceed 2.75 VDC.

– The value of R’_extshall never be less than the lowest value as indicated in table R’_ext(for V₀> V_{0 nom}) to avoid damage to the converter!

Notes:

– The R-Function excludes option P (output voltage adjustment by potentiometer).

If the output voltages are increased above V_{o nom}via R-input control, option P setting, remote sensing, or option T, the output currents should

be reduced, so that P_{o nom}is not exceeded.

– With double-output models, the second output follows the voltage of the controlled main output.

– In case of parallel connection the output voltages should be individually set within a tolerance of 1 – 2%.

Test Sockets

Test sockets (pin diameter 2 mm) for measuring the main output voltage V_oor V_o1are located at the front of the converter.

The positive test socket is protected by a series resistor (see: Functional Description, block diagrams).

The voltage measured at the test sockets is slightly lower than the value at the output terminals.

Battery Charging /Temperature Sensor

All converters with an R-input are suitable for battery charger applications, but we recommend choosing the models especially

designed for this application DK/LK1740 or DK/LK2740; see Model Selection.

For optimal battery charging and life expectancy of the battery an external temperature sensor can be connected to the R-input.

The sensor is mounted as close as possible to the battery and adjusts the output voltage according to the battery temperature.

Depending upon cell voltage and the temperature coeﬃcient of the battery, diﬀerent sensor types are available, see Accessories.

K Series

150 W DC-DC and AC-DC Converters

Installation Instructions

Note: These converters have no power factor correction (PFC). The LK4000/5000 models are intended to replace the LK1000 and LK2000

converters in order to comply with IEC/EN 61000-3-2. LK1000 is replaced by LK4003 with option K.

The converters are components, intended 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 with the enclosure,

mounting, creepage, clearance, casualty, markings, and segregation requirements of the end-use application.

Connection to the system shall be made via the female connector H15 (standard) or H15S4; see Accessories. Other installation

methods may not meet the safety requirements.

Pin no. 24 ( ) is connected with the case. For safety reasons it is essential to connect this pin reliably to protective earth.

The input pins 30/32 (Vi– or L ) are connected via a built-in fuse, which is designed to protect in the case of a converter failure.

~

An additional external fuse, suitable for the application, might be necessary in the wiring to the other input 26/28 (Vi+ or N ) or

~

even to pins 30/32, particularly if:

• Local requirements demand an individual fuse in each source line

• Phase and neutral of the AC mains are not deﬁned or cannot be assigned to the corresponding terminals.

• Neutral and earth impedance is high or undeﬁned

Notes:

– If the inhibit function is not used, pin no. 18 (i) should be connected with pin no. 14 to enable the output(s).

– Do not open the converters, or warranty will be invalidated.

– Due to high current values, the converters provide two internally parallel contacts for certain paths (pins 4/6, 8/10, 26/28 and 30/32). It is

recommended to connect both female connector pins of each path in order to keep the voltage drop low and avoid excessive connector

currents.

– If the second output of double-output models is not used, connect it parallel with the main output.

Make sure that there is suﬃcient airﬂow available for convection cooling and verify it by measuring the case temperature T_C, when

the converter is installed and operated in the end-use application; see Thermal Considerations.

Ensure that a converter failure (e.g, an internal short-circuit) does not result in a hazardous condition.

Standards and Approvals

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

The converters correspond to Class I equipment and have been evaluated for:

• Building-in

• Basic insulation between input and case based on 250 VAC, and double or reinforced insulation between input and output(s)

• Functional insulation between outputs

• Overvoltage category II

• Pollution degree 2 environment

• Max. altitude: 2000 m

• The converters fulﬁl the requirements of a ﬁre enclosure.

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

A CB-scheme is available.

Railway Applications and Fire Protection

are coated with a protective lacquer.

The converters with version V108 (or later, but not models with H15S4 connector: 5 V output without option K) comply with

NF-F16 (I2/F1). They also comply with EN 45545-1, EN 45545-2 (2016), if installed in a technical compartment or cabinet.

Protection Degree and Cleaning Liquids

Condition: Female connector ﬁtted to the converter.

• IP 30: All models except those with option P, and except those with option D or V including a potentiometer.

• IP 20: All models ﬁtted with option P, or with option D or V with potentiometer.

In order to avoid damage, any penetration of cleaning ﬂuids has to be prevented, since the power supplies are not hermetically

sealed.

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 the standard IEC 60950-1.

The following table shows some possible installation conﬁgurations, compliance with which causes the output circuit of the

converter to be an SELV circuit according to IEC 60950-1 up to a conﬁgured output voltage (sum of nominal voltages if in series

CK models ﬁtted with option E and option D6 (input voltage monitor) meet the standard ETS 300132-2 for 48 VDC supplies. Option

D6 is necessary to disable the converter at low input voltage, such avoiding an excessive input current. Connect output D (pin 20)

with inhibit (pin 18).

Option D6 should be adjusted with the potentiometer to a threshold of 36 – 40.5 V for 48 V batteries and to 44 – 50 V for 60 V

batteries. Refer also to the description of option D.

Note: Subsequent switch-on cycles at start-up are limited to max. 10 cycles during the ﬁrst 20 s (cold converter) and then to max. 1 cycle every 8s.

P Potentiometer

A potentiometer provides an output voltage adjustment range of +10/–60% of V_{o nom}. It is accessible through a hole in the front

cover. Option P is not available for battery charger models and is not recommended for converters connected in parallel.

Option P excludes the R-function. With double-output models, both outputs are inﬂuenced by the potentiometer setting (doubling

the voltage, if the outputs are in series).

Note: If the output voltages are increased above V_{o nom}via R input control, option P setting, remote sensing, or option T, the output current(s)

should be reduced, so that P_{o nom}is not exceeded.

T Current Sharing

This option ensures that the output currents are approximately shared between all parallel-connected converters, hence increasing

system reliability. To use this facility, simply interconnect the T pins of all converters and make sure that the reference for the T

signal, pin 14 (S– or Vo1–), are also connected together. The load lines should have equal length and cross section to ensure

equal voltage drops.

Not more than 5 converters should be connected in parallel. The R pins should be left open-circuit. If not, the output voltages must

be individually adjusted prior to paralleling within 1 to 2% or the R pins should be connected together.

Note: Parallel connection of converters with option P is not recommended.

D Undervoltage Monitor

The input and/or output undervoltage monitor operates independently of the built-in input undervoltage lockout circuit. A logic “low”

signal (output with self-conducting JFET) or “high” signal (NPN open-collector output) is generated at the D output (pin 20), when

one of the monitored voltages drops below the preselected threshold level V_t. This signal is referenced to S–/Vo1–. The D output

recovers, when the monitored voltages exceed V_t+ V_h. The threshold levels V_tiand V_toare either adjusted by a potentiometer,

accessible through a hole in the front cover, or adjusted in the factory to a ﬁxed value speciﬁed by the customer.

Option D exists in various versions D0 – DD, as shown in table 21. D0 and D9 are adjusted according to customer’s request and

receive a customer-speciﬁc model number.

JFET output (D0 – D4):

Pin D is internally connected via the drain-source path of a JFET (self-conducting type) to the negative potential of output 1.

V_D≤ 0.4 V (logic low) corresponds to a monitored voltage level (V_iand/or V_o1) <V_t. The current I_Dthrough the JFET should not

exceed 2.5 mA. The JFET is protected by a 0.5 W Zener diode of 8.2 V against external overvoltages.

NPN output (D5 – DD):

Pin D is internally connected via the collector-emitter path of a NPN transistor to the negative potential of output 1. V_D< 0.4 V (logic

Threshold tolerances and hysteresis:

If V_iis monitored, the internal input voltage after the input ﬁlter is measured. Consequently this voltage diﬀers from the voltage at

the connector pins by the voltage drop ∆V_tiacross the input ﬁlter. The threshold levels of the D0 and D9 options are factory adjusted

at nominal output current I_{o nom}and T_A= 25 °C. The value of ∆V_tidepends upon input voltage range (CK, DK, ..), threshold level V_t,

temperature, and input current. The input current is a function of the input voltage and the output power.

V ACFAIL signal (VME)

Available for units with V_{o nom}= 5.1 V only.

This option deﬁnes an undervoltage monitoring circuit for the input or for the input and main output voltage (5.1V) similar to option

D and generates an ACFAIL signal (V signal), which conforms to the VME standard.

The low state level of the ACFAIL signal is speciﬁed at a sink current of I_V≤ 48 mA to V_V≤ 0.6 V (open-collector output of an NPN

transistor). The pull-up resistor feeding the open-collector output should be placed on the VME back plane.

After the ACFAIL signal has gone low, the VME standard requires a hold-up time t_hof at least 4 ms, before the 5.1 V output drops

to 4.875 V, when the output is fully loaded. This hold-up time t_his provided by the internal input capacitance. Consequently the

working input voltage and the threshold level V_tishould be adequately above V_{i min}of the converter, so that enough energy is

remaining in the input capacitance. If V_iis below the required level, an external hold-up capacitor (C_{i ext}) should be added; refer to

the formulas below:

where as:

C_{i min}= internal input capacitance [mF]; see table 2

C_{i ext}= external input capacitance [mF]

in series with the input of AK – FK converters to avoid the input capacitance discharging through other loads connected to the same source voltage.

Fixed value, resistor-adjusted (±2% at 25°C) accord. to customer’s speciﬁcation; individual type number is determined by the company.

Option V operates independently of the built-in input undervoltage lockout circuit. A logic “low” signal is generated at pin

20, as soon as one of the monitored voltages drops below the preselected threshold level V_t. The return for this signal is

S–.TheVoutputrecovers,whenthemonitoredvoltagesexceedV_t+V_h.ThethresholdlevelV_tiiseitheradjustablebyapotentiometer,

accessible through a hole in the front cover, or adjusted in the factory to a determined customer-speciﬁc value. Refer to table 26.

V output (V0, V2, V3):

Pin V is internally connected to the open collector of an NPN transistor. The emitter is connected to S–. V_V≤ 0.6 V (logic low)

corresponds to a monitored voltage level (V_iand/or V_o) <V_t. I_Vshould not exceed 50 mA. The V output is not protected against

external overvoltages: V_Vshould not exceed 60 V.

Threshold tolerances and hysteresis:

If V_iis monitored, the internal input voltage is measured after the input ﬁlter. Consequently this voltage diﬀers from the voltage at

the connector pins by the voltage drop ∆V_tiacross the input ﬁlter. The threshold level of option V0 is adjusted in the factury at I_{o nom}

and T_A= 25 °C. The value of ∆V_tidepends upon the input voltage range (AK, BK, etc.), threshold level V_t, temperature, and input

current. The input current is a function of input voltage and output power.

Option K is available only for 5.1 V output models in order to avoid the connector with high current contacts. Eﬃciency is approx.

1.5% worse.

B, B1, B2 Cooling Plate

Where a cooling surface is available, we recommend the use of a cooling plate instead of the standard heat sink. The mounting

system should ensure that the maximum case temperature T_{C max}is not exceeded. The cooling capacity is calculated by (η see
