| CXA10 Series DC/DC CONVERTERS * * * * * * * * * 10W DC/DC Converters Single and dual output 1 4:1 input voltage range Approved to EN60950, UL1950, CSA C22.2 No. 950 Operating ambient temperature of -40C to +70C 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. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage accuracy Line regulation (LL to HL) Load regulation (not incl. cross reg.)
