The CXE15 is a new high efficiency open
frame isolated 15 Watt converter series in
an industry standard footprint. The first
four models in the series feature an input
voltage range of 33 to 75VDC and are
available in output voltages of 5V, 3.3V,
2.5V and 1.8V. The output voltage on
each model is adjustable from 90% to
110% of the nominal value. Typical
efficiencies for the models are 87% for the
5V, 86% for the 3.3V, 85% for the 2.5V
and 83% for the 1.8V version. The CXE15
series also has a remote on/off capability,
with active 'HI' or active 'LO' logic options
available. Overcurrent and overvoltage
protection features are included as
standard. With full international safety
approval including EN60950 and
cUL1950, the CXE15 reduces compliance
costs and time to market.

Stresses in excess of the maximum ratings can cause permanent damage to the device. Operation of the device is not implied at these or any
other conditions in excess of those given in the specification. Exposure to absolute maximum ratings can adversely affect device reliability.
All specifications are typical at nominal input Vin = 48V, full load under any resistive load combination at 25C unless otherwise stated.

Performance criteria:
NP: Normal Performance: EUT shall withstand applied test and operate within relevant limits as specified without damage.
RP: Reduced Performance: EUT shall withstand applied test. Reduced performance is permitted within specified limits, resumption to
normal performance shall occur at the cessation of the test.
LFS: Loss of Function (self recovery): EUT shall withstand applied test without damage, temporary loss of function permitted during test.
Unit will self recover to normal performance after test.
