CXA20 Series

Single and dual output

• 4:1 input voltage range

• No minimum load on singles

• 6 A on 3.3 V output (@ 48 Vin) at 50 ˚C in still air

• Wide operating temperature with overtemperature

protection

• ±10% output voltage trim

• Remote On/Off control

• Available RoHS complaint

The CXA20 is a new 20 W 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 Vdc to

75 Vdc, 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 3.3 V, 5 V, 12 V, ±5 V and ±12 V. The 3.3 V version delivering up to 6 A is

fully rated to 20 W. Typical efficiency for the CXA20 is 83%. 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
