Description

The S Series AC-DC and DC-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. LS 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 outputs can be inhibited by a logic signal applied to pin 18

(i). 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 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 and

built according to the international safety standards IEC/EN

60950 and EN50155. They have been approved by the safety

agencies TÜV and UL (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.

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 individual

applications.

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.

Important:

For applications requiring compliance with IEC/EN

61000-3-2 (harmonic distortion), please use our LS4000 and LS5000

Series with incorporated power factor correction (PFC).
