The CXA20 is a new 20W addition to the CXA family of open-frame, isolated, DC/DC
converters. The five model series features a 4:1 input voltage range of 18 to 75VDC,
making it suitable for a wide variety of communications and distributed power
applications. With its 2.0 x 1.6 inch industry standard footprint, the CXA20 provides
an easy upgrade option for new and existing Artesyn customers seeking a high-
performance, cost-effective power supply. The CXA20 is available in output voltages
of 3.3V, 5V, 12V, ±5V and ±12V. The 3.3V version delivering up to 6A is fully rated to
20W. Typical efficiency for the CXA20 is 83 percent. The CXA20 offers remote on/off,
as well as overvoltage, overtemperature and short circuit protection features.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
