APPLICATION
The WRE_S-3WR2
& WRF_S-3WR2 Series are
Patent Protected RoHS
specially designed for applications where a wide range input
voltage power supplies are isolated from the input power
supply in a distributed power supply system on a circuit
board. For these DC-DC converters, You can reduce the
design point of failure and save the development of micro
power supply‘s manpower, material and time costs, also
better ensure product quality stability, protect safety and
reliability of the end of products.
