APPLICATIONS
The WRA_YMD-3W&WRB_YMD-3W Series are
specially designed for applications where a wide range
input voltage 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.
