Description
The cabinet power changes in 25 kVA steps, so at the start several modules can be installed for the current load and more added as the hall expands. An output cos φ of 1.0 means that the kVA rating is fully available as active power in kW, with no conversion needed for server power supplies. The three-level IGBT inverter with PWM runs at 96 % efficiency in online mode, and in ECO mode this figure reaches 99 %, which shows in electricity bills for round-the-clock operation. Modules are replaced by hot swap, without switching off the load. Four cabinets are connected in parallel up to 800 kVA, so one platform covers both a small server room and a large machine hall.
How to choose
Count the modules by the load plus one spare module, so that the failure of one unit does not stop the system. If a fixed power of 30–80 kVA without expansion is needed, the single-block Maxima 3PH A3R with the same efficiency of up to 96 % online is sufficient. For 10, 15, 20 kVA there is the Maxima 3PH UR, and for desktop loads of 650–2200 VA the line-interactive Ultima S.

FAQ
How is the power of the Maxima Modular UPS increased?
Each power module is rated 25 kVA, and a cabinet holds 25–200 kVA. Up to 4 cabinets are then installed in parallel, up to 800 kVA in total.
What is the efficiency of the Maxima Modular in online mode and in ECO mode?
In online double-conversion mode the efficiency is 96 %, in ECO mode 99 %. ECO is switched on where the mains quality allows the load to be fed bypassing the inverter.
Can a UPS module be replaced without switching off the load?
Yes, the modules support hot swap. The faulty unit is pulled out, and the remaining modules in the cabinet continue to feed the load if their total power is sufficient.
What does an output cos φ of 1.0 mean for a modular UPS?
Active power in kW equals apparent power in kVA. A 25 kVA module delivers 25 kW, and no separate margin for server power supplies has to be added.
