WRA_S - 3WR2 & WRB_S - 3WR2 Series
3W,WIDE INPUT, ISOLATED & REGULATED
DUAL/SINGLE OUTPUT DC-DC CONVERTER
● External On/Off control
● High Power Density
APPLICATION
The WRA_S-3WR2 & WRB_S-3WR2 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.
These products apply to where:
