Single or Three Phase UPS - What to choose

Single-phase or three-phase UPS? What are their differences and what they offer you?

The options available in the power supply are two:

Single phase with voltage 220-230V, 1x35A with a maximum power of 8000W. Three-phase with voltage 380-430V, 3x35A with a maximum power of 24000W.

Depending on the power supply of the panel and the application that needs protection, the appropriate UPS can be used:

- Plug n' Play single-phase input/output with an apparent power of 1-3 kVA. In this class of UPS, the devices can be connected directly to the sockets available at the output.

- Single-phase input/output with grid, with an apparent power of 6-10kVA.

Tescom has 2 series of single-phase input output: the Neoline Plus, Prime Plus
