The AccuPack™ is part of the FlexPack System™ PVDT transformers from TSTM designed with 0.05% higher accuracy. The associated models (ratio’s) are for Multifunction Power Quality high accuracy solid state meters with separate metrology voltage circuits and meter power supply sources. The typical application is a substation, and industrial applications as well as control circuits. The SEL-735, ION, MaxSys Elite and JEMStar-II only mention a few multifunction meters. The transformer is individually encased in epoxy inside a flame retardant polycarbonate enclosure.

The AccuPack 2:1 ratio transformer can be used in single phase, three phase 3-wire delta applications based upon a 240V secondary. The number of transformers required are:

  • Single phase 2 or 3-wire, 480V is (1) or (2) based upon the meter Form designation
  • Three phase 3-wire delta, 480V is (2) based upon the meter Form designation
  • **Three phase 4-wire delta, 480/240V is (3) for meter Form 9S (modified) or ANSI Form109S (contact TSTM)

The AccuPack™ mounts on a required TSTM Backplane very much like a single-phase residential circuit breaker. The Backplane, which can accept up to three AccuPacks™ and optional PowerPack™, can be mounted in a pad mount transformer, transformer cabinet, in one of our enclosures designed for that purpose ( refer to “Product” page, “Enclosure” tab, Long Narrow or Universal ), or other convenient location. . The AccuPack™ is not designed to be mounted outdoors. The AccuPack™ is not designed to be mounted outdoors.
