Tripp Lite's SU60K (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. In an N+1 configuration, the SU60K features three self-contained, redundant 20kVA power modules that can be hot-swapped (with the load powered) if maintenance is required. The SU60K 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 support a variety of permanent or PDU style power connections. SU60K features 120/208V AC, 3-phase, 4-wire (plus ground), wye input and output. It also features a wide input voltage correction range: 94-150/163-260V AC. Frequency is 50 or 60 Hz (auto-selectable). SU60K features a single small-footprint tower power module.
