Tripp Lite Smart Online UPS systems offer high performance power protection ideal for critical server and network equipment in a variety of application environments. Online, double-conversion Uninterruptible Power Supply / UPS maintains perfectly regulated output power by continuously converting raw AC input to DC, then re-converting output back to AC. Sine wave AC output with +/-2% voltage regulation powers network equipment continuously, even during severe brownouts and overvoltages, all without depleting UPS battery reserves. Maintains battery-derived AC output during power failures with zero transfer time.
