CXA10-48S3V3 - Artesyn Technologies, Inc.

CXA10 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• 4:1 input voltage range

• Approved to EN60950, UL1950, CSA C22.2 No. 950

• Operating ambient temperature of -40°C to +70°C in still air

• High demonstrated reliability with conservative component

deratings

• Complies with ETS 300 019-1-3/2-3

• Complies with ETS 300 132-2 input voltage and current

requirements

• Fully compliant with ETS 300 386-1

• Pin compatible with NFC10 and BXA10 series

• Basic insulation system (input to output)

The CXA10 series comprising of five different models delivers single and dual output

voltages covering 3.3V, 5V, 12V, ±5V, ±12 and ±15V. The series has a wide 4:1 input

voltage range of 18 to 75VDC. 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 approval to EN60950 and UL1950 reducing system compliance

costs, and it has a basic insulation system from input to output making it suitable for a

wide variety of applications.
