Tripp Lite's SU80K (80kVA) SmartOnline Modular 3-Phase Intelligent, True On-Line UPS System provides 100% system availability with N+1 modular architecture and 1+1 parallel capability. In an N+1 configuration, the SU80K features four self-contained, redundant 20kVA power modules that can be hot-swapped (with the load powered) if maintenance is required. Connect two SU80K models in parallel (1+1 configuration) to provide fail-safe redundancy (two 80kVA models supporting a 80kVA load) or to increase capacity (two 80kVA models supporting a 160kVA load).The SU80K provides mission-critical equipment with the highest level of power protection available. Large capacity 80,000VA/64,000W UPS continually converts incoming AC power into filtered DC power, and then resynthesizes it back into AC power with a pure sine wave. Perfectly regulated, continuous sine wave output with zero transfer time offers compatibility with all equipment types. The SU80K's high input power factor, advanced IGBT inverter technology and Digital Signal Processor (DSP) technology create less than 3% input Total Harmonic Distortion (THDi). With SU80K's low THDi, generators run cooler and last longer, allowing managers to save installation costs by installing a generator with a capacity equal to their equipment load (a 1:1 ratio). Extremely efficient operation (up to 96%) saves money
