APPLICATIONS
The WRA(B)-YDV-3W Series are specially designed
for applications where
power supplies are isolated from the input power
supply in distributed power supply system on
circuit board. These products apply to:
a wide range input voltage

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);
Note: Metal package style series is WRA_YDV-3W & WRB_YDV-3W.
3) Where the regulation of the output voltage and the
output ripple noise are demanded.
