Description

The M Series of DC-DC and AC-DC converters represents a

broad and flexible range of power supplies for use in advanced

industrial electronic systems. Features include high efficiency,

reliability, low output voltage noise and excellent dynamic

response to load/line changes due to individual regulation of

each output.

Full input to output, input to case, output to case, and output to

output isolation is provided.

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 should remain below 95°C under all conditions.

The converter inputs are protected against surges and

transients occurring 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.

A temperature sensor generates an inhibit signal, which

disables the outputs, when the case temperature T_Cexceeds

the limit. The outputs automatically recover, when the

temperature drops below the limit.

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.

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 60927-3 or be mounted onto a chassis or a

plate.

LED indicators display the status of the converter and allow

visual monitoring of the system at any time.
