APPLICATIONS
The KRB_S-1W series are specially designed
for applications where a wide range input voltage
power supplies are unnecessary 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 isolation is unnecessary between input
and output;
3) Where the regulation of the output voltage and
the output ripple/noise are not demanding.
