Description
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.
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.
