Snaptec Australia has introduced its new series of DC UPS units with built in batteries for DC standby applications. The ADU series feature a battery charger and battery in a compact unit.

The ADU series is available in voltages of 12V , 24V , 36V and 48V with power levels ranging from 300W to 1KW.
Some of the features of these units include:
- active PFC >0.95
- automatic battery low voltage disconnect (LVD)
- charging voltage adjustment
- short circuit
- over voltage and over temperature protection
- built-in cooling fan on-off control .
The ADU series are designed for low cost bulk power dc ups applications.
