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