The WPA50 uses unique proprietary technologies to deliver ultra-high efficiencies and excellent thermal performance. It includes extensive control and protection features for maximum flexibility and provides a versatile solution for a whole range of applications with its input voltage range of 36-75 VDC and output voltages between 1.2VDC and 5.0VDC. The power dissipation of the WPA50 series is so low that a heat sink is not required. The product features fast dynamic response characteristics and low output ripple critical for low voltage Output Overcurrent Protection Hiccup Mode Input Side “L” Filter No Minimum Load Required No Heatsinks Low Profile and Low Weight Thermal Shutdown Remote On/Off Control Isolation Voltage of 1500 VDC Soft Start High Reliability Fixed Frequency Operation Safety per UL/CUL 60950, EN 60950, Operational Insulation Meets TNV-SELV Isolation Requirements Meets Conducted Emissions Requirements of FCC Class B and EN55022 Class B applications. WPA DC-DC converter modules are certified to UL/CUL 60950, and VDE to EN60950. It meets CISPR22/ EN55022/FCC15J Class B specs for EMI levels with external filtering. This high quality and highly reliable product is competitively priced and an ideal solution for distributed power, telecoms and datacom applications.
