APPLICATION

The WRE_S-3WR2

& WRF_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)

3KVDC input and output isolation;

3)

Regulated and low ripple noise is required.

Such as: industrial control, telecommunication etc.
