DESCRIPTION
The WRB-YES-1W&WRB-YES-2W 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.
