3-30W Dual Isolated Regulated Outputs DC/DC converters R3 Series


Mornsun recently added four new series with dual isolated regulated outputs to its wide input R3 DC/DC converters family, URD-S-3WR3, URD48-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.
