TECHNICAL SPECIFICATIONS
EWS SERIES - 5 WATT
REV. 12/01
EWS DC/DC converters offer excellent regulation and
isolation in an industry-standard package.
The EWS
series is ideal for industrial, datacom, or telecom
applications. The EWS series features short circuit pro-
tection, six-sided shielding, and 500 VDC isolation.
Please see the EWD series for dual-output applications.
