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 TV 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
TC 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.
