Tripp Lite's SU60KTV (60kVA) SmartOnline Modular 3-Phase Intelligent, True On-Line UPS System provides 100% system availability with N+1 modular architecture and 1+1 parallel capability. Connect two SU60KTV models in parallel (1+1 configuration) to provide fail-safe redundancy (two 60kVA models supporting a 60kVA load) or to increase capacity (two 60kVA models supporting an 120kVA load). The SU60KTV provides mission-critical equipment with the highest level of power protection available. Large capacity 60,000VA/48,000 watt UPS continually converts incoming AC power into filtered DC power, and then resynthesizes it back into AC power with a pure sine wave. Hardwire input and output connections. SU60KTV features 277/480VAC, 3-phase, 4-wire (plus ground), wye input and output. It also features a wide input voltage correction range (218-348/378-603VAC at full load). Frequency is 50 or 60 Hz (auto-selectable).
