XWS SERIES - 150 WATT
DESCRIPTION
XWS DC/DC converters are high-powered converters
which cover a wide range of industrial and general
applications. Available input voltages include 12V, 24V,
40V, and 48V; output voltages are available from 5V to
24V. The XWS features remote sense leads for accurate
point of load regulation, and has short circuit and overcur-
rent
protection. For dual and triple output high power
solutions, see the XWD and XWT series of converters,
respectively.
