The CXE15 is a new high efficiency open frame isolated 15 Watt converter series
in an industry standard footprint. The CXE15 features an input voltage range of 33
Vdc to 75 Vdc and are available in output voltages of 5 V and 3.3 V. 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 5 V and 86% for the 3.3 V. The
CXE15 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 CXE15
reduces compliance costs and time to market.

The CXE15 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 116 for details.
4
Recommended input fusing is a 2 A HRC 200 V rated fuse.
5
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6
Measured with external filter. See Application Note 116 for details.
7
Start-up into resistive load.
8
Signal line assumed < 3 m in length.

Remote ON/OFF (pin 3) and Trim (pin 5) are currently available individually
or together. The CXE-48S05J model includes pins 1, 2, 4, and 6. The
CXE15-48S3V3-SJ features pin 3 with positive logic.
11
This parameter is calculated at worst case line, load, temperature and initial
settings.
