The MWS series of DC to DC converters provides up to 20W of output power in the
industry standard 1.6” x 2” package and footprint. The MWS is available in 24V and
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 1500VDC of isolation, shortcircuit, and overtemperature protection.
The MWS is 100% surface mount construction and is built in IPD’s fully automated ISO
9001 factory located in Boston.
