The WRA_CS-1W & WRB_CS-1W 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);
3.3

(9.0-18)
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.
