BWD SERIES - DUAL OUTPUT, 2.5 WATT

DESCRIPTION FEATURES

BWD dual output DC/DC converters offer excellent regulation and isolation in an industry standard DIP package. With several input voltage ranges, the BWD is perfect for industrial, telecom, and networking applications. The BWD features short circuit protection, low profile, and 500 VDC isolation. Please see the BWS series for single output applications.
