DESCRIPTION
The SW3R W Series is a 1500Vdc isolated range of single and dual output 3W DC-DC converters, designed with a 2:1 input
voltage range and ideal for use in a whole variety of telecoms, industrial and distributed power applications. Available in industry
standard E and L DIP packages (32 x 20 x 9 mm), the SW3R W is fully encapsulated in a metal case and is designed to meet
EN60950 and UL1950 safety standards. Continuous SC protection and UVLO are some of the many SW3R W features.
