Tripp Lite's SmartOnline SUINT1500RTXL2Ua online, double conversion UPS protects critical server, networking and telecommunications equipment from blackouts, voltage fluctuations and transient surges. Large capacity 1.5kVA/1200 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%). Removes harmonic distortion, fast electrical impulses, frequency fluctuations and other hard-to-solve power problems not addressed by other UPS types. Pure sine wave output and zero transfer time to battery offers guaranteed compatibility with all equipment types. Highly efficient operation in optional Economy Mode setting, saving BTU heat output and energy costs. Includes 6 IEC-320-C13 outlets arranged in two individually switchable load banks of three outlets each. Load banks can be controlled independently via software interface to selectively reboot remote equipment or shed less important loads to extend battery runtime for critical equipment. Battery backup runtime can be extended through the addition of external battery packs BP48V24-2U (limit 1), BP48V60RT-3U (multi-pack compatible) and BP48V27-2US (multi-pack compatible). Network management interfaces support simultaneous communications via USB port, DB9 serial port and SNMPWEBCARD slot.
