    Latest R3 Series of Dual Isolated Regulated Outputs DC/DC converters released, have strong EMI ability

    Mornsun recently added four new series with dual isolated regulated outputs to its wide input R3 DC/DC converters family, URD-S-3WR3, URD-YMD-10WR3, URD-LD-20WR3 and URD480524D-30WR3 series. These four new series adopt international standard pins, have strong EMI ability and good compatibility. Besides, the series provide a 4:1 ultra wide input voltage range, and deliver efficiencies up to 84%.

    In addition to meeting EN62368 standards, protections for input under-voltage, output short circuit, over-current are also included. Applications include data transmission device, Tele-communication device, distributed power supply system, hybrid A/D system, remote control system, etc.


    • Primary/Secondary output are positive
    • Ultra wide input voltage range(4:1): 18~75VDC
    • Efficiency up to 84%
    • Isolation voltage: 1500VDC/3000VDC/3000VAC
    • Protections including input under-voltage, output short circuit, over-current
    • Operating temperature range: URD-LD-20WR3 is -40℃ to +105℃, other series are -40℃ to +85℃
