Power protection and battery backup for home and office computers and electronics. Protects your valuable equipment from damage, downtime and data loss. Features called automatic voltage regulation (AVR) that solves the problem. The UPS detects when input voltage is out of bounds and corrects it without using the battery. Also features a LCD screen that shows a variety of helpful data, including input voltage, battery capacity, power status, battery status and AVR status. Design saves energy, produces less heat and shrinks your carbon footprint and reduces annual costs.
