Compared with PSU Series, PNC have the follwing advantages:
- Nickel-cadmium and lead-acid batteries,
- Charging voltage and
- Charging current adjustable

There is a 50Ah standby battery setting, a external battery higher than 50Ah can be connected too.
Apply AC commercial power as their primary power and battery as standby power.
In case of commercial AC power cut, the PNC series can seamless switch to standby power supply automatically.
