Description
Air Cooled 3 Phase Servo Stabilizers are an effective solution to the problem of Voltage fluctuations that occur. These fulfill the need of an interface between an unregulated power supply & sophisticated equipment requiring highly regulated AC input Voltage. The stabilizers will safeguard, costly equipments from Voltage variations and provide guaranteed performance by improving the reliability. These are designed to give a stabilized output within ± 10/0 of the present Voltage adjustable between 220V and 240V.These servo voltage stabilizers contain a motorized auto-transformer which boosts or bucks input supply to give a stabilized output. A solid state of Art Technology is used for designing the control circuit.
