APPLICATIONS
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);
2) Where isolation is necessary between input and output
(Isolation Voltage ≤ 1000VDC);
3) Where isolation is necessary between Vout1 and Vout2
(Isolation Voltage ≤ 1000VDC);
