3kVA on-line double-conversion UPS with 3U rackmount and interactive LCD display. Ideal for critical server and network equipment in datacenters, computer rooms and network closets. Maintains perfectly regulated output power by continuously converting raw AC input to DC, then re-converting output back to AC. Fully regulated sine wave AC output with +/-2% voltage regulation powers network equipment continuously, even during severe brownouts and overvoltages, all without depleting UPS battery reserves.
