The WRA_P-3WR2 & WRB_P-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 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.
These products apply to where:
1) Input voltage range ≤2:1;
2) 1.5KVDC input and output isolation;
3) Output regulated and low ripple noise is required.
In circuits such as industrial control, electric power, communication system power supply, etc.
