The KRB_D-3W 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 dem anding.
3) Where the regulation of the output voltage and
the output ripple noise are not dem anding.
