Microprocessor-Controlled Fully Automatic Protected Three-Phase Servo Voltage Regulator

The microprocessor-controlled, fully automatic, protected three-phase servo voltage regulator is a professional energy stabilisation system that instantly analyses unstable and fluctuating voltage from the mains supply to provide a constant, safe and balanced output voltage. Developed specifically for industrial facilities, production lines, and high-power three-phase devices, this model offers precise regulation performance thanks to its variable motor technology and microprocessor-controlled structure.

Sudden surges, drops and phase imbalances in the mains voltage can cause serious malfunctions in sensitive equipment such as CNC machines, automation systems and medical devices. A three-phase servo voltage regulator eliminates these risks, ensuring the safe and uninterrupted operation of systems.

Working Principle

Device, each phase separate separate monitored microprocessor controlled control card with operates. Mains voltage is continuously measured and variac motor system via automatically as corrected. There is a separate digital screen for each phase. These screens both input and output voltage display and also control panel as function performs. Thus the user system parameters easily monitor and when necessary adjust.
