HP Series
120 - 192 Watt 10:1 DC-DC Converters
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 total current limitation, extremely high
efficiency, excellent reliability, very low ripple and RFI noise
levels, full input-to-output isolation, negligible inrush current,
soft start, over temperature protection, interr uption time, and
input over- and undervoltage lockout.

120 - 192 W 10:1 DC-DC Converters
Description
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 converter covers a total input voltage range from 12.5 to 154 VDC in the same model. The input is protected against
surges and transients occurring on the source lines. The outputs are continuously open- and short-circuit proof.
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 con verters with T option are connected in parallel, a single-wire connection between
these converters ensures good current sharing. LEDs at the front panel and an isolated output OK signal indicate the status of the
converter. Voltage suppressor diodes and an independent overvoltage monitor protect the outputs against an internally generated
over voltage.
The converters are designed using transformers with planar technology. The input voltage is fed to a booster, which generates
approximately 70 V. If V is higher, the booster becomes simply a diode. The resulting intermediate voltage supplies the powertrains.
i
There are 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 inductors together with circuit symmetry ensure
a small deviation between main and tracking output.
A storage capacitor charged to approx. 70 V enables the powertrains to operate during the specified interruption time.
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 3 U /4 TE only, but they can also be chassis-
mounted by screws or fitted with a heat sink. The connector type is H15. The fully enclosed black-coated aluminum case acts as
heat sink and RFI shield, such protecting the converter together with the coating of all components against environmental impacts.
