The WPN20R series is a family of
high performance DC/DC converters
available in three input voltage ranges
of 9-18V, 18-36V and 33-75V. The unit
is housed in a space saving aluminum
shell and combines low cost with high
performance across all line and load
conditions. The 300KHz switching
frequency and forward converter
topology provide excellent performance
across all line and load conditions in a
space saving package. Other features
include: full regulation down to zero
load, under voltage lock-out, internal
temperature shutdown, soft start, remote
on/off and over current protection.
An output trim feature is provided,
allowing the user to compensate for long
line lengths. The WPN20R Series is
assembled using a fully automated
process incorporating 100% surface
mounted components for increased
reliability.
Applications include: Telecom-
munications, Battery Powered Sytems,
Process Control Equipment,
Transportation Equipment and
Distributed Power Systems.
