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.
