APPLICATION

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.

These products apply to where:

1)

Input voltage range

≤2:1;

2)

Input and output isolation

≤3KVDC;

3)

Regulated and low ripple noise is required.

Such as: industrial control, telecommunication etc.
