A Servo Voltage Stabilizer is an advanced electrical device used to maintain stable output voltage automatically, regardless of voltage fluctuations from the grid. Designed with a servo motor-controlled mechanism, these stabilizers offer high accuracy, making them ideal for industrial machinery, medical equipment, printing units, CNC machines, laboratories, and more.

Why you need a Servo Voltage Stabilizer?

It is seen that in spite of best efforts by various Electricity Boards / Supply undertakings the voltage at consumer’s end is never constant. The reason being diverse loading duties arising in transmissions and distribution network. During the day time when the load requirements is more the voltage remains quite low and during night it goes up than the normal. As a result of these never ending voltage fluctuations there is frequent tripping / breakdown of the systems / machines and precious equipment’s resulting into low production. Our servo voltage stabilizer can overcome and control these voltage fluctuations & can provide you with the desired constant output voltages. Every servo voltage stabilizer rolled out of the factory undergoes strict and rigid inspection and testing. Our servo voltage stabilizer are available in vast choice of input and output voltage range suitable for various applications in industries, institutions and residences etc. having indigenous, imported sophisticated machines / instruments / gadgets etc.

How Does this Servo Voltage Stabilizer Operate?

Servo voltage stabilizer essentially a solid-state circuit, which controls the servo motor. The motor is mechanically coupled to the arm of a continuously variable auto transformer (Variac) that feeds to the primary of a series control buck-boost transformer. The stabilizer output voltage is compared with the reference voltage and the resultant error signal controls the servo motor providing true proportional control systems rather than on/off circuits.

Type of Servo Voltage Stabilizer?

Unbalanced Type : Widely accepted design to suit various conditions. All the phase/s are independently sensed & corrected. Suitable for both balanced / unbalanced loading & incoming voltage.

Balanced Type : One phase (master) sensed & all the 3 corrected in accordance to the master phase. Suitable for balanced loading & balanced incoming voltage only (not suitable for unbalanced loading / unbalanced input voltage).
