Description

The H Series of AC-DC converters represents a flexible range

of power supplies for use in advanced industrial electronic

systems. Features include high efficiency, reliability, and low

output voltage noise.

The converter inputs are protected against surges and

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

undervoltage lockout circuit disables the outputs, if the input

voltage is outside the specified range. An inrush current

limitation prevents 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 the

connector (pin 2). 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 60950-1 and have been approved by the safety

agencies TÜV and UL.

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, when the case temperature

exceeds

the limit. The outputs automatically recover, when the

temperature drops below the limit.

Two options are available to adapt the converters to individual

applications (D, V).

The converters may either be plugged into 19" rack system

according to IEC 60927-3 or be mounted onto a chassis or a

plate.
