Description
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.
