The CXA10 series comprising of five different models delivers
single and dual output voltages covering 3.3 V, 5 V, 12 V, ±5 V, ±12
V and ±15 V. The series has a wide 4:1 input voltage range of
18Vdc to 75 Vdc. The CXA10 has been designed as a competitive
open-frame alternative for the communications market. The
product is supplied in the industry standard footprint of 2.0 x 1.0 x
0.394 inches. Other product features include overvoltage
protection, short-circuit protection and remote ON/OFF.
All components are placed in a fully automated environment.
Planar magnetics are used in the design to improve the reliability
and reduce the profile of the dc-dc converter. The series has full
international safety approvals reducing system compliance costs,
and it has a basic insulation system from input to output making it
suitable for a wide variety of applications.
