The WRE_P-3WR2 & WRF_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) Where the voltage variation range of the input power supply ≤ 2:1;

2) Where isolation is necessary between input and output (isolation voltage ≤3KVDC);

3) Where high requirements for the output voltage stability and output ripple noise are applied;

In circuits such as industrial control, electric power, communication system power supply, etc.
