This VersaPack™ is one of three Precision Voltage Dividing Transformers (PVDTs) needed for 480/277 4-wire wye applications where traditional 2.4:1 VT's are used. For all other 480V applications, we recommend other versions; see our “Product” page for various options. This VersaPack™ consists of one revenue-accuracy toroidal autotransformer for use with modern wide voltage range electronic watthour meters or older induction (disk-type) meters. The transformer is encased in epoxy inside a flame retardant polycarbonate enclosure.  

The VersaPack™ mounts on a required TSTM Backplane very much like a single-phase residential circuit breaker. The Backplane, which can accept up to three VersaPack's™, 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. . Many meter socket manufacturers offer “extended” sealed compartments to accommodate the VersaPack / Backplane isolating the 480 volts. The VersaPack™ is not designed to be mounted outdoors.
