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.

(9.0-18)
These products apply to:
9
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.
