FEATURES
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.

They are not intended to be subject to surface mount processes under any circumstances. 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.
