EWD dual output DC/DC converters offer excellent

regulation and isolation in an industry standard

package. Available in several input versions, the EWD

is perfect for industrial, datacom, or telecom

applications. The EWD features short circuit

protection, six-sided shielding, and 500 VDC isolation.

Please see the EWS series for single output

applications.
