Tripp Lite's SmartOnline SU3000XL on-line, double conversion UPS protects critical server, networking or telecommunications equipment from blackouts, brownouts, voltage fluctuations and surges in an attractive all-black tower format. Large capacity 3kVA / 2400 watt UPS continuously converts incoming AC-to-DC, then back to perfect sine wave AC output at 120V AC (+/-2%). Removes harmonic distortion, fast electrical impulses, frequency fluctuations and other hard-to-solve power problems not addressed by other UPS systems. True sine wave output and zero transfer time offers guaranteed compatibility with all equipment types. Includes 7 UPS supported outlets with two individually switchable load banks that can be independently controlled via the UPS's software interface to selectively reboot remote equipment or automatically shed less critical loads to extend battery runtime for the most critical equipment. Battery support can be extended with the addition of multiple external battery packs (part# BP72V9). Includes slot for internal SNMP/web card, plus DB9 enhanced serial monitoring port for unattended shutdown, remote control and monitoring of UPS system and power data. Includes Tripp Lite's PowerAlert UPS Power Management Software. Compatible with Tripp Lite's WatchDog Service Monitoring/Rebooting Software.
