DESCRIPTION
EWS DC/DC converters offer excellent
regulation and isolation in an industry standard
package. Available in 5V or 12V input versions,
the EWS is ideal for industrial, datacom, or
telecom applications. The EWS features short
circuit protection, six-sided shielding, and 500
VDC isolation. Please see the EWD series for
dual output applications.

Notes
1 Converter will auto-restart once fault has been removed.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully
compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please
consult factory for specific model information.
