The WRD_YS-1W & WRD_YS-2W 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);
5
200/200
111/111
83/83
20/20
11/11
8/8
2) Where isolation is necessary between input
and output (Isolation Voltage≤ 1000VDC);
3)Where isolation is necessary between Vout1
and Vout2 (Isolation Voltage≤ 1000VDC);
4) Where the regulation of the output voltage
and the output ripple noise are demanded.
