TECHNICAL SPECIFICATIONS
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 feature short circuit protection, six-sided
shielding, and 500 VDC isolation. Please see
the EWD series for dual output applications.
