The Powercom King Pro KIN-2200AP is a microprocessor controlled line-interactive UPS designed to provide high-performance power protection for mission critical environment equipment such as file servers, internet servers, network back-up drives, hubs, and telecommunication systems. Under normal conditions, the line-interactive circuit adjusts and filters power fluctuations continuously and automatically, ensuring that all connected devices are operating with constancy and stability. In the event of power failure, the UPS seamlessly transfers to battery power without interruption. The maintenance-free sealed Lead-Acid battery lets the UPS run for 85-95 minutes, so you have time to close files and protect data. It also protects your data lines against surges, spikes, lightning, and other power disturbances. The included UPSMON power management software automatically saves and closes open files and shutdowns the PC in an intelligent and orderly fashion, with audible and visible alarms.
