Sine wave tower uninterruptible power supply (UPS) offers network-grade power protection for your critical server, network and telecommunications equipment. Line-interactive UPS with built-in, auto-voltage regulation (AVR) actively corrects brownouts and overvoltages back to usable levels while maintaining a full battery charge in case of power failure. Super-fast switchover from line to battery power occurs within milliseconds to maintain operation of connected equipment without interruption. 95 percent line-mode efficiency offers reduced heat emissions and operating costs. Network management interfaces support communications via USB and RS-232 network interfaces. HID-compliant USB port enables integration with built-in power management and auto shutdown features of Windows and Mac OS X operating systems. Network communication ports enable detailed monitoring of equipment load levels, self-test data and utility power conditions.
