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 50121-2-3.
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 case design allows operation at nominal load up to 71 °C
in a free-air ambient temperature. If forced cooling is provided,
the ambient temperature may exceed 71 °C, but the case
temperature must remain below 95 °C under all conditions.
The converter inputs are protected against surges and
transients. 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.
A temperature sensor generates an inhibit signal, which
disables the outputs when the case temperature TC exceeds
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.
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.
The converters may either be plugged into a 19" rack system
according to IEC 60297-3, or be chassis mounted. They are
ideally suited for Railway applications.
LED indicators display the status of the converter and allow for
visual monitoring of the system at any time.
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).

The control logic senses the main output voltage Vo1 and
generates, with respect to the maximum admissible output
currents, the control signal for the switching transistor of the
forward converter.
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 the power during the hold-up time.
The second output of double-output models is tracking to 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.
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.
Standard models with a single 5.1 V output have a
synchronous rectifier to provide good efficiency.

Input Transient Protection
Inrush Current Limitation
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.
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.
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%.
The inrush current peak value (initial switch-on cycle) can be
determined by following calculation; see also fig. 3:
In certain applications, additional surges according to RIA 12
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.

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 200 VDC, an
external fuse or a circuit breaker at system level should be
installed.

Input Under-/Overvoltage Lockout
If the input voltage remains below approx. 0.8 Vi min or exceeds
approx. 1.1 Vi max, an internally generated inhibit signal
disables the output(s). When checking this function, the
absolute maximum input voltage Vi abs should be observed.
Between Vi min and the undervoltage lock-out level the output
voltage may be below the value defined in table Electrical

applied overvoltages. Overload at any of the outputs will
cause a shut-down of all outputs. A red LED indicates the
overload condition.
Thermal Considerations
If
a converter is located in free, quasi-stationary air
(convection cooling) at the indicated maximum ambient
temperature TA 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 TC (see Mechanical Data) will approach the
indicated value TC max after the warm-up phase. However, the
relationship between TA and TC depends 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. TA max is therefore, contrary to TC max, an indicative
value only.
Note: Vo 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.
Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table
Temperature specifications.
Notes:
– Parallel connection of double-output models should always
include both, main and second output to maintain good
regulation.
Notes: Sufficient forced cooling or an additional heat sink allows
TA to be higher than 71 °C (e.g., 85 °C), as long as TC max is not
exceeded. Details are specified in fig. 8.
– 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.

A temperature sensor generates an internal inhibit signal,
which disables the outputs, when the case temperature
exceeds TC 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

Sense Lines (Single-Output Models)
Auxiliary Functions
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.
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!
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:
Note: If pin 18 is not connected, the output is disabled.

Notes:
Double-output models:
– The R-Function excludes option P (output voltage adjustment by
potentiometer).
Wiring of the R-input for output voltages 24 V, 30 V, or 48 V
with both outputs in series. A ceramic capacitor (Co) across
the load reduces ripple and spikes.
If the output voltages are increased above Vo nom via R-input
control, option P setting, remote sensing, or option T, the output
currents should be reduced, so that Po nom is not exceeded.
– With double-output models, the second output follows the
voltage of the controlled main output.
positive test jack is protected by a series resistor (see:
Functional Description, block diagrams).
– In case of parallel connection the output voltages should be
individually set within a tolerance of 1 – 2%.
The voltage measured at the test jacks is slightly lower than
the value at the output terminals.
Test Jacks
Test jacks (pin diameter 2 mm) for measuring the main output
voltage Vo or Vo1 are located at the front of the converter. The

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

Installation Instructions
Safety and 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.
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 or H15-
S4 connector. The protective earth is connected by a leading
pin (no. 24), ensuring that it makes contact with the female
connector first.
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.

Pin no. 24 ( ) is connected with the case. For safety reasons
it is essential to connect this pin reliably to protective earth.
Type H15
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+

Notes:
Cleaning Agents
– If the inhibit function is not used, pin no. 18 (i) should be
connected with pin no. 14 to enable the output(s).
In order to avoid possible damage, any penetration of
cleaning fluids has to be prevented, since the power supplies
are not hermetically sealed.
– 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.
Protection Degree
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.
– If the second output of double-output models is not used,
connect it parallel with the main output.
• IP 20: All models fitted with option P, or with option D or V
with potentiometer.
Make sure that there is sufficient airflow available for
convection cooling and verifiy it by measuring the case
temperature TC, when the converter is installed and operated
in the end-use application; see Thermal Considerations.
Railway Application
The 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.
Ensure that a converter failure (e.g., an internal short-circuit)
does not result in a hazardous condition.
Standards and Approvals
Isolation and Protective Earth
The converters are safety-approved to UL 60950-1, CSA
60950-1, IEC 60950-1, and EN 60950-1.
The electric strength test is performed in the factory as routine
test according to EN 50116 and IEC/EN 60950 and should not
be repeated in the field. Power-One will not honor any
warranty claims resulting from electric strength field tests.
The resistance of the earth connection to the case (<0.1 Ω) is
tested as well.
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)
Leakage Currents
Leakage currents flow due to internal leakage capacitances
and Y-capacitors. The current values are proportional to the
supply voltage and are specified in the table below.
• Functional insulation between outputs
• Overvoltage category II
• Pollution degree 2 environment
• Max. altitude: 2000 m
LK Models Operated at Greater than 63 Hz
Above 63 Hz, the earth leakage current may exceed 3.5 mA,
the maximum value allowed in IEC 60950. Frequencies ≥ 350
Hz are only permitted with Vi ≤200 VAC.
• The converters fulfill the requirements of a fire enclosure.
The converters are subject to manufacturing surveillance
in accordance with the above mentioned standards and ISO
9001:2000. A CB-scheme is available.
The built-in Y-caps are approved for ≤100 Hz. Safety approvals
and CB scheme cover only 50 – 60 Hz.

CK/DK/EK/LK models may be supplemented by an electronic

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.

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 Vt. This signal is
referenced to S–/Vo1–. The D output recovers, when the
monitored voltages exceed Vt + Vh. The threshold levels Vti
and Vto are 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.

Threshold tolerances and hysteresis:
If Vi is monitored, the internal input voltage after the input filter

the input filter. The threshold levels of the D0 and D9 options
are factory adjusted at nominal output current Io nom and TA =

Note: Option V2 and V3 can be adjusted by the potentiometer to

converters to avoid the input capacitance discharging through
other loads connected to the same source voltage.
V ACFAIL signal (VME)
Available for units with Vo nom = 5.1 V only.
This option defines an undervoltage monitoring circuit for the
input or for the input and main output voltage ( 5.1 V) similar to
option D and generates an ACFAIL signal (V signal), which
conforms to the VME standard.
Option V operates independently of the built-in input under-
voltage 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 Vt. The return for this signal is
S–. The V output recovers, when the monitored voltages
exceed Vt + Vh. The threshold level Vti is either adjustable by a
potentiometer, accessible through a hole in the front cover, or
adjusted in the factory to a determined customer-specific
value. Refer to table 26.
The low state level of the ACFAIL signal is specified at a sink
current of IV ≤ 48 mA to VV ≤ 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 th of 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 th is provided by the internal input capacitance.
Consequently the working input voltage and the threshold
level Vti should be adequately above Vi min of the converter, so
that enough energy is remaining in the input capacitance. If Vi
is below the required level, an external hold-up capacitor
(Ci ext) should be added; refer to the formulas below:
V output (V0, V2, V3):
Pin V is internally connected to the open collector of an NPN
transistor. The emitter is connected to S–. VV ≤ 0.6 V (logic
low) corresponds to a monitored voltage level (Vi and/or Vo)
<Vt. IV should not exceed 50 mA. The V output is not protected
against external overvoltages: VV should not exceed 60 V.

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

calculated by (η see Model Selection):
For the dimensions of the cooling plates, see Mechanical
Data. Option B2 is for customer-specific models with
elongated case (for 220 mm DIN-rack depth).
