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.

132 Watt DC-DC Converters
The current limitation is located at the primary side, thus
limiting the total output current in overload conditions. This
allows flexible loading of each output for unsymmetrical loads
in the range 10 to 90% of the total output power. In applications
with large dynamic load changes, we recommend connecting
such a load to output 1. If output 2 is not used, it should be
connected parallel to output 1. Both outputs can either be
series- or parallel-connected (see
Electrical Output Data).
In normal operation, the internal control circuits are powered
by a third winding of the main choke (except 48 Q models).
Start-up is ensured from the input voltage by a linear regulator.
Note:
When the output voltage is much lower then the nominal
value, this linear regulator is activated, generating considerable
power losses.
Functional Description
The converters are designed as forward converters using
primary and secondary control circuits in SMD technology. The
switching frequency is approximately 200 kHz under nominal
operating conditions. The built-in high-efficient input filter
together with a small input capacitance generate very low
inrush currents of short duration. After transformer isolation
and rectification, the output filter reduces ripple and noise to a
minimum without compromising the dynamic ability. The
output voltage is fed to the secondary control circuit via
separate sense lines. The resultant error signal is sent to the
primary control circuit via a signal transformer.
Double-output models have the voltage regulation of output 2
relying on the close magnetic coupling of the transformer and
the output inductor together with the circuits' symmetry.
