Description
The increased power density comes from a three-level IGBT inverter with PWM, which reduces losses and heating. In online mode efficiency reaches 96 %, and in the economy ECO mode 99 %, when the load is fed through the bypass while the inverter is in hot standby. The boards have a protective coating, and a dust filter is fitted at the air inlet, so the UPS tolerates dusty rooms better. The battery string is configurable from 32 to 44 blocks, which makes it possible to match the bus voltage to the batteries on hand, and the OBM function is supported. The unit is operated from a 5-inch color touchscreen with a menu in 10 languages.
How to choose
The rating is determined by the active load, and because of cos φ of 1.0 no margin is added for the reactive component. The number of battery blocks within 32–44 is chosen together with the runtime. If the load exceeds 80 kVA, move to Maxima 3PH A2R of 100–200 kVA with paralleling of up to 4 UPS units, and for a small server room of 10–20 kVA Maxima 3PH UR is enough.
