What is a three phase ups?

The three phase UPS can be subdivided into three phase input/three phase output UPS system and three phase input/single phase output system types. If you need to connect to a three phase supply, you must need a UPS with a 3/x configuration. A 3/1 UPS takes in 3 phase power but delivers single phase to the downstream load while a 3/3 UPS not only takes in but also puts out 3 phase power.

Three-phase UPS use three separate conductors providing three sinewaves, each out of phase and spaced 120° apart from each other, to provide continuous power to the load. This means a three-phase system needs a minimum of four wires (three conductors plus one neutral), which enables it to support a single-phase or three-phase output.  

Three-phase UPS are the standard choice for larger installations with critical loads such as data centres, industrial applications, and medical environments, as well as protecting equipment with motors such as lifts, pumps, and fans.
