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.

NOTE: Other input to output voltages may be available. Please consult factory.
