The WPA50 Series a 50 Watt single output, low-profile DC-DC converter in an industry standard package x 9.0mm). The WPA50 uses unique proprietary technologies to deliver ultrahigh 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

applications. WPA DC-DC converter modules are certified to UL/CUL 60950, and VDE 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.
