Minuteman Ships New Three-Phase UPS
     

Para Systems Minuteman EnTerra UPS
Para Systems’ Minuteman line of power protection devices offers a new tool, the EnTerra three-phase backup uninterruptible power supplies.

EnTerras are available in 50/60 Hz, 10–40 kVA models (10, 15, 20, 30, and 40kVA). They use double conversion technology and Adaptive Feed Cancellation for large electrical load protection. Minuteman says, “The combination of centralized backup, high input and output power factors (0.99 and 0.9 respectively), and up to 94% system efficiency ratings mean EnTerra offers a substantial reduction in operating costs versus multiple single phase UPSs. Users can also reduce electrical consumption and operating costs when upgrading from older, less efficient 3-phase systems.”

Features include an SNMP communications card, monitoring software and internal bypass hardware. EnTerra installations are expandable in parallel for increased capacity or N+1 redundancy — up to 160 kVA, according to Minuteman. Spec sheet is here
