Tripp Lite's SmartOnline SU10KRT3UHV on-line, double conversion UPS protects server, networking or telecommunications equipment from blackouts, voltage fluctuations, and surges in a compact tower/rackmount housing. In rack configuration, power module, and battery pack occupy only 3 rack spaces each (6U total). Large capacity 10, 000VA / 7000 watt power module converts raw input AC to DC, then back to perfect sine wave AC output within 2% of user-selectable 200/208/220/230/240V AC output voltages. Frequency regulation locks output power to 50/60Hz (+/-0.2 Hz), removing harmonic distortion, fast electrical impulses and other hard-to-solve power problems not addressed by other UPS types. Perfectly regulated, continuous sine wave output with zero transfer time offers guaranteed compatibility with all equipment types. Hardwire input and output connections support a variety of permanent or PDU style power connections. Battery support can be extended indefinitely through the addition of external 3U rackmount battery packs (part# BP240V10RT3U). 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.
