APPLICATIONS

The RSB_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.
