PART NUMBER SYSTEM
APPLICATION
The WRA_P-3WR2
& WRB_P-3WR2 Series are
WRA2405P-3WR2
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
failure points of design, and save the manpower, material
and time cost in developing micro power supply, and also
ensure better quality, stability, safety protection, and
reliability for the end products.
