Featuring true on-line operation with pure sine wave output, zero transfer time to battery and complete UPS replacement capability with no downtime, the SU6000RT4UHV provides the highest level of protection available for mission-critical equipment from power outages, voltage fluctuations and transient surges. It converts incoming AC power to DC, and re-converts it back to filtered AC output with a pure sine wave, isolating connected components from all power problems in high-voltage environments. The SU6000RT4UHV has a 6kVA / 5400W capacity and four AC outlets (two L6-20R; two L6-30R).With its detachable PDU, the SU6000RT4UHV is easily hot-swappable by a user of any skill set; no need for lengthy and expensive service calls, and no downtime if a repair or battery replacement is needed. In bypass mode, the PDU passes power to equipment without the use of the power and battery modules, allowing them to be removed while keeping your application in operation. UPS battery backup keeps connected equipment operational through short power failures, and provides time to save data and perform an orderly system shutdown in case of a prolonged blackout. The SU6000RT4UHV‘s runtime can be expanded with optional external battery packs. The SU6000RT4UHV features a highly efficient (96%) economy mode setting that can significantly reduce a facility's energy costs by minimizing heat output, reducing cooling requirements and consuming less electricity. An LCD display with LED indicators enables IT personnel to monitor operating modes and conditions. The LCD / LED panel rotates for viewing in horizontal rack or vertical tower installations and includes an audible alarm that signals various conditions. The SU6000RT4UHV features a USB port and a DB9 port that, when used with PowerAlert software, provides comprehensive network power monitoring and control. An optional network management card accessory, enables the UPS to operate as an IP managed device. The unit requires only 4U of rack space in a standard rack enclosure and can be installed in a 2-post rack using the 2POSTRMKITHD accessory or in a tower configuration with the 2-9USTAND accessory.
