Automatic Voltage Regulator

Prima Automation’s microcontroller based

Prima Automation’s micro controller based servo voltage stabilizer are designed to provide constant output voltage at a continuous load. The stabilizer protects against Short Circuit, Overload Protection, Over Voltage, Under Voltage and Over Current thus leading to low maintenance and reduction in breakdowns. The stabilizer protects expensive electrical equipment from voltage fluctuations and thus leading to low maintenance, it is also used for energy saving. It is applicable to CNC Machinery, Electrical/Electronic equipment, Medical Equipment, Residential/Commercial application and Lifts/elevators/escalators.
