IWS SERIES
10 WATT
DESCRIPTION
IWS DC/DC converters offer excellent regulation
and isolation in an industry standard package.
Available in several input versions, the IWS is
perfect for industrial, datacom, or telecom
applications. The IWS features short circuit
protection and 500 VDC isolation. Please see the
IWD series for dual output applications.

Notes
1 Continuous short circuit protection is provided. Long-term
continuous operation in this mode is not recommended.
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 com-
patible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model.
Please consult factory for specific model information.
