Three Phase UPS
A three phase UPS system utilises all three phases produced by the grid, consisting of 3 separate sine waves, each out of phase by 120 degrees. This means that three phase systems use a four wire configuration, three live conductors and a neutral, which enables 3 Phase UPS systems to support either three or single phase output. Due to the increased amount of live connections required, three phase installations require more cabling work than a single phase installation.
Three phase UPS systems operate with a voltage of 400/415VAC and are used more often than not for larger installations, such as data centres , hospitals and industrial applications.
Key Differences
- Three Phase UPS offer higher efficiency
- Number of live wires and sine waves
- Single Phase involves less cabling work to install
- Single Phase UPS are only available up to 20kVA
- Voltage (230VAC Single Phase vs 415VAC Three Phase)
