APPLICATIONS
15

20
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)
2)
3)
Where the voltage of the input power supply is
wide range (Voltage range≤2:1);
9
333
33
Where isolation is necessary between input and
output (Isolation voltage≤1500VDC);
12
250
25
Where the regulation of the Output voltage and
the output ripple noise are demanded.
