APPLICATIONS

The KRB_P Series are specially designed

for applications where a wide range input

voltage power supplies are non-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.

2) Where the regulation of the output voltage

and the output ripple noise are not

demanding.

3) Where the regulation of the output voltage

and the output ripple noise are not

demanding.
