Single Phase UPS
A single phase UPS operates with a single input source, and a single output source to electrical equipment. With only a single sine wave voltage, single phase supplies operate with a two wire configuration; one live conductor and one neutral. Each single phase supply is typically derived from a larger three phase supply.
An example of single phase supply is a standard UK 3 Pin wall socket, which supplies 230/240VAC single phase electricity for smaller applications.
Single phase UPS ranges typically cover power requirements up to 20kVA and are used most often to protect equipment such as rack mounted servers/switches, telecoms devices and CCTV.
