High Eficiency
The WPN20RC 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 WPN20RC 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.

The normal wave soldering process can be used with these devices
where the device is subjected to a maximum wave temperature of
260°C for a period of no more than 10 seconds. Within this time and
temperature range, internal temperatures within the converter will not
exceed 175°C. Care should be taken to control manual soldering limits
identical to that of wave soldering.
