Ensto Voltage Controller is a single-phase voltage controller for low voltage distribution grids.
It is installed close to consumer interface, where it measures the feeding line voltage and stepwise adjusts the output voltage. The unit is able to increase and decrease the line voltage level.
The output control range is -10% - +15% and the voltage increase/decrease function is selected automatically based on the locally measured voltage. The boosting function is active, while the input v
