APPLICATIONS

The WRB_T-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.
