APPLICATIONS

The WRA_YD-3W&WRB_YD-3W 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.
