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 Systems, Process Control
Equipment, Transportation Equipment and Distributed Power Systems.
Operating Temperature Range: -40°C to +115°C
