Description
DSP-based control keeps the output sine wave stable regardless of the mains condition, so the load sees only the inverter. Active power is 0.9 of the rating, which must be taken into account when sizing a server rack. In ECO mode efficiency rises to 98 %, which reduces heating and electricity bills when the mains is clean. The CVCF mode turns the UPS into a frequency converter with constant output voltage, needed for equipment designed for a different mains frequency. Up to 3 UPS units are connected in parallel for redundancy or to add power.
How to choose
The rating is chosen by the sum of the load with a margin and taking cos φ of 0.9 into account. For one rack 2 or 3 kVA is usually enough, and for a small server room or communication node 6 or 10 kVA. When more than 10 kVA or a three-phase input is needed, look at Maxima 3PH UR of 10–20 kVA. For office PCs, where a line-interactive scheme is sufficient, the simpler option is Ultima S.

CVCF means constant voltage and frequency at the output; in this mode the UPS works as a frequency converter.
What power ratings are in the Maxima Online range?
Models of 2, 3, 6 and 10 kVA with an output cos φ of 0.9 are made.
Can single-phase Maxima Online UPS units be paralleled?
Yes, up to 3 UPS units work in parallel, which gives redundancy or more power.
What is the efficiency of Maxima Online?
Up to 98 % in ECO mode and less in double-conversion mode, but with no switching at all.
Is Maxima Online suitable for telecom equipment?
Yes, the manufacturer intends this series for data centers, telecommunications and security systems, where the load must be powered with no pause.
