DESCRIPTION
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.
