APPLICATIONS

The VRA_D-10W & VRB_D-10W 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.
