Description
The inverter works into an output isolation transformer, so the load is separated from the battery circuit and the mains. The base VEGA has three configurations: 10–100 kVA with a three-phase input and a single-phase output, 10–200 kVA in a 3/3 arrangement, and the HP version of 100–600 kVA with an IGBT rectifier. The standard rectifier is a 6-pulse thyristor one, and a 12-pulse one is available to order, which reduces input current harmonics. The IGBT rectifier with power factor correction distorts the mains very little and is easier to match with a diesel generator. VEGA HE is designed for 100–800 kVA and reaches an efficiency of up to 95.5 % in online mode and up to 99.4 % in stand-by mode. Besides double conversion, the UPS works in ECO mode, as a frequency converter or as a stabilizer.
How to choose
The choice starts with the load phase count and power, then the rectifier type is determined by the requirements for input harmonics and generator compatibility. For power-hungry halls from 100 kVA, VEGA HE with higher efficiency is more cost-effective. Up to 8 UPS units are connected in parallel for N+1 redundancy or for adding power. If an isolation transformer is not needed and compactness and modularity matter, look at HELIOS-TH of 10–100 kVA with an efficiency above 95.5–96 %.

FAQ
Why does the VEGA UPS have an output transformer?
It provides galvanic isolation of the load from the battery and the mains, which is needed for medical systems and industrial processes with sensitive grounding circuits.
What is the efficiency of the VEGA HE UPS?
Up to 95.5 % in double-conversion mode and up to 99.4 % in stand-by mode at power ratings of 100–800 kVA.
How many VEGA UPS units can be connected in parallel?
Up to 8 UPS units run in parallel for redundancy or to increase system power.
What rectifier is fitted in the VEGA UPS?
By default a 6-pulse thyristor one, optionally a 12-pulse one, and the HP version of 100–600 kVA has an IGBT rectifier with power factor correction.
Can VEGA work as a frequency converter?
Yes, besides the online mode and ECO, the UPS can be set up as a frequency converter or a voltage stabilizer.
