WPN20
20W Regulated DC/DC Converter
FEATURES
RoHS compliant
Operating temperature range: -40ºC to
+100ºC
Industry standard pinout
Input and output filtering
Low profile shell
Single and dual outputs
Output trim function
DESCRIPTION
The WPN20RC series is available in three input
voltage ranges of 9-18V, 18-36V and 33-75V. The
unit is housed in a space saving aluminum shell.
The 300KHz switching frequency and forward
converter topology provide excellent performance
across all line and load conditions. Other features
include: under voltage lock-out, internal tem-
perature shutdown, soft start and over current
protection.
An output trim feature is provided, allowing the
user to compensate for long line lengths.
Applications include: Telecommunications, Battery
Powered Sytems, Process Control Equipment,
Transportation Equipment and Distributed Power
Systems.
The product range has been recognised by Under-
writers Laboratory (UL) to UL 1950 for operational
insulation, file number E179522 applies.
