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.
