Tripp Lite Smart Online UPS 3000VA 2700W 208/120V Step-Down Transformer 4U - UPS (rack-mountable) - 20 A - AC 208 V - 2.7 KW - 3000 VA - RS-232, USB - Output Connectors: 20 - 4U - 19" - SU3000LCD2UHVTF

This 208V and 120V 60 Hz UPS system maintains perfect output by converting AC input to DC, then reconverting UPS output to fully regulated sine wave AC with +/-2% voltage regulation in both on-line and battery modes. Featuring a 2.7kW capacity, high 0.9 power factor, 570 joules of surge suppression, true on-line operation with pure sine wave output and zero transfer time in on-line double-conversion mode, the SmartOnline SU3000LCD2UHVTF double-conversion UPS provides the highest level of AC power protection and battery backup for critical network closet, computer room and data center equipment. With the included 2U step-down transformer, this 3kVA UPS system can support both low- and high-voltage equipment.
Pick your power strategy, from precise power for sensitive systems to the highest possible electrical efficiency, while ensuring 100% uptime. Choose from four selectable strategies: Max Efficiency, Max Quality, Frequency Regulation and Auto Adaptive, which automatically offers increased efficiency when utility power conditions are good and enhanced power quality when power conditions are poor.
The UPS and transformer combined feature 20 outlets in total - 12 unswitched NEMA 5-15/20R on the transformer, six NEMA 6-15/20R on the UPS and one unswitched NEMA L6-20R on each. Four NEMA 6-15/20R outlets are split into two switchable load banks, allowing you to reboot select components or shed loads remotely.
The field-replaceable, hot-swappable internal battery provides 13.5 minutes of support at half load (1350W) and five minutes at full load (2700W), keeping protected equipment operational through power failures. For mission-critical applications demanding scalable extended runtime, the UPS supports "smart" external battery packs, such as Tripp Lite's BP72V18-2US (sold separately). Both the internal batteries and sensor-enabled external battery packs are automatically sensed and configured during installation and replacement to offer accurate remaining runtime during outages and battery-age notifications. The intelligent battery management system with temperature-compensated charging extends battery life.
Auto-bypass mode keeps connected equipment powered and operational, even during UPS fault conditions.
Battery-independent restart ensures automatic UPS power-up without user interaction after lengthy power outages, even when batteries are expired and require replacement.
The front-panel LCD screen reports UPS operating mode, detailed UPS status and site-power information, as well as a variety of advanced UPS setup and configuration options. LEDs indicate AC input/output, battery and fault status.
RS-232 and HID-compliant USB ports connect to a computer running Tripp Lite's free downloadable PowerAlert software to enable safe unattended file saves and system shutdown in case of a prolonged power failure. An EPO port connects the UPS to a contact closure switch to enable emergency inverter shutdown. Cables are included.
An accessory slot accommodates the optional Java-free HTML5-based WEBCARDLX (sold separately) that enables full remote access for site power and UPS status monitoring, configuration, control and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Automated alerts help prevent accidental
