The LK 4000/5000 Series of AC-DC converters represents

a flexible range of power supplies for use in advanced

electronic systems; the LKP models are an extension with

increased output power, but optimized to 230 VAC.

Features include full power factor correction, good hold-up

time, high efficiency and reliability, low output noise, and

excellent dynamic response to load/line changes.

The converters are protected against surges and

transients occurring at the source lines. Input over- and

undervoltage lockout circuitry disables the outputs, when

the input voltage is outside of the specified range. Input

inrush current limitation is included for preventing circuit

breakers and fuses from tripping at switch-on.

All outputs are overload, open- and short-circuit proof, and

protected by a built-in suppressor diode. The outputs can

be inhibited by a logic signal applied to connector pin 18. If

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 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 and built according to the international safety

standards IEC/EN 60950-1 2 nd Ed. They have been

approved by the safety agencies TüV and CSA (for USA

and Canada).

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. However, higher output power up to 280 W is

possible depending on environmental conditions and

converter model.

An internal temperature sensor generates an inhibit signal,

which disables the outputs, when the case temperature T C

exceeds the limit. The outputs automatically recover, when
