50 W DC-DC and AC-DC Converters
Description
The M Series of DC-DC and AC-DC converters represents a broad and flexible range of power supplies for use in advanced in -
dustrial 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.
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.
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 con-
nected 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 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.
A temperature sensor generates an inhibit signal, which disables the outputs, when the case temperature TC exceeds the limit.
The outputs automatically recover, 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 60927-3 or be mounted onto a chassis or a plate.
Model Selection
Non-standard input/output configurations or special custom adaptions are available on request. Table 1 provides an overview of
the basic input and output configurations. More than 1000 different model types have been manufactured with di ff erent input/output
configurations and customized specialties. Please consult the company for additional model types.
