Summary

The K series of AC-DC (DC-DC) converters represents a

flexible range of power supplies for use in advanced elec-

tronic systems. Features include wide input frequency

range (no PFC), high efficiency, high reliability, low output

voltage noise and excellent dynamic response to load/line

changes.

The converter inputs are protected against surges and tran-

sients occuring at the source lines. An input over- and

undervoltage lock-out circuitry disables the outputs if the

input voltage is outside the specified range. Certain types

include an inrush current limitation preventing circuit break-

ers and fuses from being damaged at switch-on.

All outputs are open- and short-circuit proof and are pro-

tected against overvoltages by means of a built-in suppres-

sor diode. The outputs can be inhibited by a logic signal ap-

plied to the connector pin 18 (i). If the inhibit function is not

used pin 18 must be connected to pin 14 to enable the out-

puts.

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 modules are designed

and built according to the international safety standards

IEC/EN 60950 and have been approved by the safety

agencies LGA (Germany) und UL (USA). The UL Mark for

Canada has been officially recognized by regulatory au-

thorities in provinces across 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.

A temperature sensor generates an inhibit signal which

disables the outputs if the case temperature

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 in-

dividual applications.

The modules may either be plugged into 19" rack systems

according to DIN 41494, or be chassis mounted.

Important:

For applications with requirements for com-

pliance with IEC/EN 61000-3-2 (harmonic distortion)

please use our LK 4000 and LK 5000 series.
