WRB11005YMD-6W
The WRA_YMD-6W&WRB_YMD-6W 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.
72-144
*Input voltage can't exceed this value,or will cause the permanent damage.

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.
