Description
These extremely compact DC-DC converters incorporate all
necessary input and output filters, signaling and protection
features, which are required in the majority of applications.
The converters provide important advantages such as flexible
output power through primary current limitation, high
efficiency, excellent reliability, very low ripple and RFI noise
levels, full input to output isolation, negligible inrush current,
overtemperature protection, and input over-/undervoltage
lockout. The converter inputs are protected against surges
and transients occurring on the source lines.
The converters are particularly suitable for rugged
environments, such as railway applications. They have been
designed in accordance with the European railway standards
EN 50155 and EN 50121-3-2. All printed circuit boards are
coated with a protective lacquer.
The outputs are continuously open- and short-circuit proof. An
isolated output Power Good signal and LEDs at the front panel
indicate the status of the converter. Test sockets at the front
panel allow for a check of the main output voltage.
Full system flexibility and n+1 redundant operating mode are
possible due to virtually unrestricted series or parallel
connection capabilities of all outputs. In parallel connection of
several converters, automatic current sharing is provided by a
single-wire interconnection.
As a modular power supply or as part of a distributed power
supply system, the extremely low profile design significantly
reduces the necessary power supply volume without
sacrificing high reliability. A temperature sensor disables the
outputs, if the case temperature exceeds the limit. The outputs
are automatically re-enabled, when the temperature drops
below the limit.
The fully enclosed, black-coated aluminum case acts as a heat
sink and an RFI shield. The converters are designed for 19"
DIN-rack systems occupying 3 U / 4 TE only, but can also be
chassis-mounted by means of four screws. Fitting an
additional heat or ordering options with fitted heat sink is
possible as well.
