APPLICATIONS
The WRA_YD-3W&WRB_YD-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.
