UNIKOMPENZATOR 400 is active compensator of power factor, in accordance with the requirements of power distribution companies. Maintains the desired power factor by the creation of inductive or capacitive reactive power. Standard control range of power factor cos φ is from 0.95 capacitive to 0.95 inductive (this parameter is configurable for the whole PVP). Active compensator can be supplied even for higher power factor ranges (0.9 capacitive to 0.9 inductive), if requested.

UNIKOMPENZATOR 400 is a transformerless inverter designed for direct connection of a inverter or arbitrary number of parallel ranged inverters on the primary side of the grid transformer with ratio 0.422 kV.
