Servo Stabilizer is the equipment which provides stable output voltage to load. Generally, it has been experiential that there is never a stable supply of voltage in AC Main Supply. Frequently, it varies from 150V-300V and 300V to 500 Volt. Therefore, due to which the severe situation can come out like Over Load situation, Heavy Line Losses, Poor Power Factor, Problem of Machinery Damage, and other. The mechanism selected in manufacturing ensures fast and high modification ratio to be maintained against voltage variation through the operation. These dedications have ensured difficulty free and efficient process for both small size equipment and heavy electrical equipment.
