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.

(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.

shutdown; It should be note that the input current
(Ic) should between 5-10mA, exceeding the
