APPLICATIONS

The WRA_CS-2W & WRB_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 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.
