APC Back-UPS Pro

Notifies users when the status of the power supply or UPS system changes. Periodic battery self-tests allow for timely replacement of depleted batteries. Automatically increases low voltage gradually and reduces high voltage to levels suitable for your devices. Early detection analysis of battery faults enables timely preventive maintenance. Allows for quick and easy battery replacement. Reserves capacity and backup time for connected devices that need to switch to UPS battery operation in an emergency; less critical devices are only protected from surges. Enhances UPS availability by correcting over- and under-voltages without using the battery. Enables temporary battery operation when the mains supply fails. Protects connected devices from surges on data lines. Patent-pending operating mode that switches off unused electrical components under good power supply conditions, achieving very high operational efficiency without compromising safety.
