APPLICATIONS

The

WFB_CS-2W

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.

These products apply to:

1) Where the voltage of the input voltage range:

2:1;

2) Where isolation is necessary between input

and output(Isolation Voltage≤2000VDC);

3) Where the regulation of the output voltage and

the output ripple noise are demanded.
