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 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.

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 V_o1and

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

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 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

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 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.

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.

Caution: The installer must ensure that under all operating

conditions T_Cremains 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

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.

– 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 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

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 (C_o) across

the load reduces ripple and spikes.

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.

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 V_oor V_o1are 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+

or N ) or even to pins 30/32, particularly if:

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 T_C, 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 V_i≤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.

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_ti

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 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 ( 5.1 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 V_t. The return for this signal is

S–. The V output recovers, when the monitored voltages

exceed V_t+ V_h. The threshold level V_tiis 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 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_i

is below the required level, an external hold-up capacitor

(C_{i 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–. 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.

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 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).
