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.
