APPLICATIONS
The WRA_YD-2W&WRB_YD-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≤1500VDC);
3) Where the regulation of the output voltage and the
output ripple noise are demanded.
