Description
Double conversion under the control of a digital signal processor (DSP) means the load is always powered from the inverter and does not see mains transients. An output cos φ of up to 1.0 gives the full active power in kW with no loss on the reactive component. In ECO mode efficiency reaches 99 %, and this mode is appropriate to use when the mains is stable. Up to 3 UPS units are connected in parallel, so power or redundancy is added without replacing the unit. Monitoring goes through Ethernet and a cloud service, WLAN is available as an option, and locally the status is visible on the color touchscreen. The three-phase input loads the supply evenly, unlike a single-phase UPS of the same rating.
How to choose
The rating of 10, 15 or 20 kVA is chosen by the peak load with a margin for expansion. If the site has only single-phase supply, Maxima Online of 2–10 kVA is better. For a load of 30–80 kVA move to Maxima 3PH A3R with a three-level IGBT inverter and a battery string of 32–44 blocks.

FAQ
What ratings does the Maxima 3PH UR three-phase UPS have?
The range includes models of 10, 15 and 20 kVA with an output cos φ of up to 1.0.
How many Maxima UR units work in parallel?
Up to 3 UPS units are connected in parallel for redundancy or to increase system power.
How can Maxima 3PH UR be monitored remotely?
The UPS has an Ethernet port and a cloud connection, and a WLAN module is installed as an option.
What is the efficiency of Maxima UR?
In ECO mode efficiency reaches 99 %, and in online mode it is lower because of the double conversion of energy.
Why is double conversion in Maxima UR better than a line-interactive scheme?
The inverter runs all the time, so the load does not feel any switching, unlike line-interactive UPS units such as Ultima S of 650–2200 VA.
