IWD SERIES - DUAL OUTPUT, 10 WATT
DESCRIPTION
FEATURES
IWD dual output DC/DC converters offer excellent
regulation and isolation in an industry-standard package.
Available in 5V and 12V input versions, the IWD is
perfect for industrial, datacom, or telecom applications.
The IWD features short-circuit protection and 500 VDC
isolation. Please see the IWS and IAS series for single
output applications.
