The SU3000RTXLCD3N SmartOnline® 120V 3kVA 2.7kW 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 four NEMA 5-15R and four 5-15/20R outlets in switchable numbered load banks, as well as one L5-30R outlet and an L5-30P input, the SU3000RTXLCD3N has an internal battery that provides 11 minutes of support at half load and four minutes at full load. Adding external battery packs, such as BP72V15-2U (sold separately), provides extended runtime. The pre-installed WEBCARDLX network interface permits full remote access for site power and UPS status monitoring, configuration, control and email notifications via secure web browser, SNMP, telnet or SSH. An interactive LCD panel 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-joule surge suppression rating protects your equipment from harmful power surges. With Tripp Lite’s free downloadable PowerAlert® software, SU3000RTXLCD3N enables safe unattended system shutdown and file saves in case of a prolonged power failure.
