APPLICATIONS
The WRA_YD-4W & WRB_YD-4W 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.
