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. For dual and triple output high power solutions, see
the XWD and XWT Series of converters, respectively.
