Description

The H series of DC-DC converters represents a broad and

flexible range of cassette power supplies for use in

advanced electronic systems. Features include high

efficiency, reliability, and reasonable output voltage noise.

The converter inputs are protected against surges and

transients occuring at the source lines. Input over- and

undervoltage cut-out circuitry disables the outputs if the

input voltage is outside the specified range.

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 the connector pin 2 (i). If the inhibit

function is not used, pin 2 should be connected to pin 23 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

standard IEC/EN 60950 and have been approved by the

safety agencies TÜV and UL (USA and Canada).

The case design allows operation at nominal load up to

50 °C in a free air ambient temperature. If forced cooling is

provided, the ambient temperature may exceed 50 °C, but

the case temperature should remain below 80 °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 19-inch rack

systems according to DIN 41494, or be chassis mounted.
