CXA10 SERIES Single and dual 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 openframe 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.
