CXA10 Series
Single and dual output
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.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
