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.
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 UL/CSA 60950-1, and they have been
approved by the safety agencies TV and UL.
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.
