DESCRIPTION
The WRA_YMD-10W & WRB_YMD-10W 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.
*Input voltage can't exceed this value,or will cause the permanent damage.
