Remote on/off control
The SXE15 is a new high efficiency open frame isolated 15 Watt converter series in
an industry standard footprint. All models in the series feature an input voltage range
of 33 to 75VDC and are available in output voltages of 12V, 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 12V and 83% for the 1.8V version. The SXE15 series also has a
remote on/off capability with active high or active low logic. Overcurrent and
overvoltage protection features are included as standard. With full international
safety approval including EN60950 and cUL1950, the SXE15 reduces compliance
costs and time to market.
