The Tripp Lite SU2200RTXLCDN SmartOnline(R) 120 V 2.2 kVA 1.8 kW on-line double-conversion UPS provides battery backup and AC power protection against blackouts, brownouts, power surges, and line noise that can damage electronics or destroy data. It converts AC input to DC power, and then converts DC to fully regulated sine wave AC output with +/-2% voltage regulation in online and battery modes. Featuring six (6) NEMA 5-15/20R outlets in two (2) switchable numbered load backs, as well as one (1) L5-20R outlet and a 5-20P input, the SU2200RTXLCDN has an internal battery that provides 12 min of support at half load and 4 min at full load. Adding external battery packs, such as BP48V24-2U (sold separately), provides extended runtime. The pre-installed SNMPWEBCARD accessory card permits remote management, including reboots, configuration, updates and activity logs. An interactive front-panel LCD interface displays operating conditions and diagnostic data, such as load, voltage, and battery levels. You can set operating modes to reflect your protection priorities, including an optional economy mode that saves heat output and energy costs. EMI/RFI noise filtering improves your equipment’s performance and prevents damage. A 570 J surge suppression rating protects your equipment from harmful power surges. With Tripp Lite’s included POWERALERT12 software, the SU2200RTXLCDN enables safe unattended system shutdown and file saves in case of a prolonged power failure.
