APPLICATIONS
The WRD_YD-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 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.
