Output
The WRA_YMD-5W& WRB_YMD-5W series
are specially designed for applications where a
group of polar 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.
