MWS SERIES - 20 WATT
DESCRIPTION
FEATURES
MWS DC/DC converters provide up to 20 watts of output
power in an industry-standard package and footprint. The
MWS is available in either 24V or 48V input versions.
With a maximum case temperature of 100°C, the MWS is
well suited for the most demanding telecom, networking,
and industrial applications. The MWS features 1500 VDC
isolation, short circuit, and overtemperature protection.
