Magnetic Induction Automatic Voltage Stabilizer

Intact Controls, IR & IR3 Series Voltage Stabiliser / Regulator utilizes the latest in Magnetic Induction technology to ensure the mains voltage remains constant at all times. As a Magnetic Induction based solution, IR&IR3 stabilisers utilise a simple, yet highly reliable, rotor and stator design principle to increase or reduce the magnitude of the voltage in a series transformer winding, thereby delivering and maintaining a constant output voltage. The arrangement is similar to a motor, except that the rotor does not rotate continuously. Its maximum rotation is only 130 degrees. Themagnetic coupling between the rotor (the shunt winding) and stator (Series Winding) will cause the magnitude of the voltage in the series winding to increase or decrease, depending on the angle or position of the rotor to the stator. For example, when the input voltage drops, the rotor will rotate clockwise to such an angle to make up for the drop in voltage, rotating anti-clockwise to correct for a high voltage.
