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-side current limitation,
extremely high efficiency, excellent reliability, very low ripple
and RFI noise levels, full input-to-output isolation, negligible
inrush current, soft start, overtemperature protection and
input over- and undervoltage lockout.
The converters are particularly suitable for rugged environ-
ments, 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 converter inputs are protected against
surges and transients occurring on the source lines and cover
a total operating input voltage range from 16 to 150 VDC
with five different model types. The outputs are continuously
open- and short-circuit proof.

90 – 192 Watt DC-DC Converters
Full system flexibility and n+1 redundant operating mode are
possible due to series or parallel connection capabilities of the
outputs under the specified conditions. When several
converters (with 3.3 and 5.1 V outputs) are connected in
parallel, the T option allows for a single-wire connection
between the converters to ensure good current sharing. LEDs
at the front panel and an isolated Out-OK signal (option)
indicate the status of the converter. Voltage suppressor
diodes and an independent second control loop protect the
outputs against an internally generated overvoltage.
The converters are designed using planar magnetics
transformers and control circuits in hybrid technology. There
are always two powertrains fitted to a converter, each con-
sisting either of a regulated single output with synchronous
rectifier or of a regulated main output with a tracking second
output. The output power may be flexibly distributed among
the main and the tracking output of each powertrain. Close
magnetic coupling in the transformers and output conductors
together with circuit symmetry ensure tight tracking of the
auxiliary output. The switching frequency is fixed.
As a modular power supply or as part of a distributed power
supply system, the low-profile design significantly reduces the
required volume without sacrificing high reliability. The
converters are particularly suitable for 19" rack systems
occupying 3U/4TE only, but they can also be chassis-
mounted by means of four screws. Connector type is H15 (or
H15S2 for some single-output models). The fully enclosed
black-coated aluminum case acts as heat sink and RFI shield
and protects the converter together with the coating of all
components against environmental impacts.

90 – 192 Watt DC-DC Converters
Output Configuration
The P Series allows high flexibility in output configuration to
cover almost every individual requirement, by simply wiring
outputs in parallel, in series, or in independent configuration,
as shown in the following diagrams.
Parallel or serial operation of several converters with equal
output voltage is possible, however it is not advantageous to
01006-P
connect converters in parallel without measures to provide
reasonable current sharing. Choose suitable single-output
models, if available.
Note:
Unused tracking outputs should be connected parallel to the
respective regulated output.
