The WattBox® UPS battery pack is loaded with features to help keep vital equipment up and running in the case of power loss. This Pure Sinewave UPS provides battery backup and full automatic voltage regulation (AVR) to prevent costly interruptions, as well as a 'Graceful Shutdown' of a connected PC via USB port. By using the single outlet to back up a WattBox IP power conditioner, you can receive system OvrC updates, which allow you to monitor power and perform basic functions like load shedding configuration. With this model, you’ll get a 1100 VA capacity, up to 3:30 minutes of battery backup at full load (900W), and at least 9 minutes of battery backup at 50% load (450W).
