A device that is used to control the fall of the voltage of one or more phases and their asymmetry sequence
in three-phase circuits 400 Vol ac.
* The output relay is activated when the supply and the sequence of three phase is correct.
* Ability to set the overvoltage and undervoltage limit.
* 3 sec delay at on and 1 sec delay at cut off time.
