Tripp Lite's high voltage SmartOnLine SU3000RTXL3UHV on-line, double conversion UPS protects critical server, networking or telecommunications equipment from blackouts, voltage fluctuations and surges. Multi-use form factor occupies only 3 rack spaces (3U) in standard 19-inch rackmount configuration and includes tower stands and removable rack hardware to support tower and stacking applications. Large capacity 3kVA / 2400 watt UPS continuously converts incoming AC to DC, then back to perfect sine wave AC output at selectable 200/208/220/230/240V AC (+/-2%) output. It removes harmonic distortion, fast electrical impulses, frequency fluctuations and other hard-to-solve power problems not addressed by other UPS types. True sine wave output and zero transfer time offers guaranteed compatibility with all high-voltage equipment types. It includes 8 outlets arranged in two individually switchable load banks and 1 L6-20 outlet. These outlet banks can be independently controlled via software interface to selectively reboot remote equipment, or shed less critical loads to extend battery runtime for more critical equipment. Battery support can be extended indefinitely through the addition of external 2U rackmount battery packs. The SU3000RTXL3UHV includes a 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. It is compatible with Tripp Lite's WatchDog Service Monitoring/Reboot Software.
