A three-phase installation uses the full three phases which are generated from the grid. A three phase electrical supply comprises of three individual sine waves, and can be installed as either a three wire or three wire & neutral configuration. A three-phase source would typically come from a local transformer, with the standard three phase voltage being 400/415 VAC.10-600 kVA
Understanding the total kVA requirement of a critical load is a key part of establishing a UPS’ true sizing requirement. For more information see kVA calculator and guide to choosing a UPS.Standalone
Standalone UPS systems allow several units to be operated in tandem (known as horizontal scaling) to provide for a greater load.
