DESCRIPTION
The SW3R UWSM Series is a 1500Vdc isolated range of single and dual output 3W DC-DC converters, designed with a 4:1
input voltage range and ideal for use in a whole variety of telecoms, industrial and distributed power applications. In an industry
standard surface mount packages (33 x 16 x 11 mm), the SW3R UWSM is fully encapsulated in a non-flammable plastic case
(meeting UL 94V-0) and is designed to meet EN60950 and UL1950 safety standards. Continuous SC protection and UVLO are
some of the many SW3R UWSM features.
