Note: Metal package style series is WRA_YDV-3W & WRB_YDV-3W.
The WR A (B)-YDV -3W 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.
