APPLICATION
Patent Protected RoHS
The WRE_S-1WR2 & WRF_S-1WR2 Series are 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.
