The PUPS series is a desk top DC UPS that is powered by either a 5VDC input source (for a 5V output) or 12VDC input source (for a 12V output) from a standard AC-DC power adaptor.
The output is battery backed by internal lithium batteries in the event of an AC mains failure. The charger uses a constant current, constant voltage, standby charge battery management system.
It can be used with any approved AC-DC power adaptor which has sufficient output power to provide the load and charge the internal batteries of the UPS. These products are available with 2 battery ratings of either 22.2 or 44.4 Watt hours.
