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:

1) Input voltage range

≤2:1;

2) 1.5KVDC input and output isolation;

3) Regulated and low ripple noise is required.

Such as: industrial control, tele-communications etc.
