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 dem anded.
