APPLICATIONS

APPLICATIONS

The WR-YD-20W(2.16) 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 power

supply is wide range (Voltage range≤2:1);

2)Where isolation is necessary between

input and output (Isolation voltage≤1500VDC);

3)Where the regulation of the Output voltage

and the output ripple noise are demanded.
