Trusted Servo Voltage Stabilizer Manufacturer in Jaipur India

Introduction of Servo Voltage Stabilizer

Highly fluctuating AC mains supply is a very common occurrence in India, and the difficulties caused by them are well known. The servo voltage stabilizer maintains the amount of voltage in the power system even in the event of voltage fluctuations. Stable input supply is a basic requirement in the absence of which sophisticated equipment does not deliver optimum performance.

Major industrial loads are inductive (i.e., AC motors), and they draw quite a lot of current at high and low voltages resulting in high losses, which in turn increase the temperature of the motors, thereby reducing motor life. Other types of equipment affected by high and low voltages are lighting loads (bulbs and tubes), air conditioning plants, elevators and elevators, medical equipment, etc.

To overcome this problem,Shakti Electrical Corporation offers the best quality servo voltage stabilizer that ensures constant output voltage, thus providing complete protection and optimum efficiency of all electrical & electronic equipment. Furthermore, the motors operate smoothly without drawing excess current by installing the shakti servo voltage stabilizer and maintaining the output voltage of 400V 3-0 /230V, 1-0 within 1%.


Shakti Electrical Corporation's 3 Phase servo voltage stabilizers are manufactured using separate controls for each phase, thus making them suitable for unbalanced input voltage and load current and supplying the remaining types of units on demand.

Basic Concept of Shakti Servo Stabilizer

The Shakti servo stabilizer consists of a solid-state circuit that controls the servo motor. The motor is mechanically connected to a continuously variable auto-transformer arm that feeds the primary of the buck/boost transformer. The stabilizer output voltage is compared to the reference voltage, and the resulting error signals control the servo motor providing a true proportional control system rather than an on/off the circuit.

Leading Servo Stabilizer/Servo Regulator Manufacturer and Exporter in Jaipur Rajasthan

Shakti Electrical Corporation is here with the new servo voltage stabilizer for home or commercial purpose such as linear type servo voltage stabilizer, roller type voltage stabilizer, dimmer type voltage stabilizer, which protects all electrical equipment from fluctuating currents. Servo voltage regulator manufacturer mentions that the stabilizers are of 3 phases, and individual controls are used for each phase to make it perfect for the fluctuating input voltage. We as a top servo voltage stabilizer manufacturer in India designs the product in a way that saves a lot of power consumption up to 15% and also helps to increase the efficiency of your electrical equipment.

To buy a shakti servo voltage regulator or stabilizer is to provide a life backup to your electrical equipment as the unbalanced input voltage damages the household electrical equipment to a great extent and hence results in less efficiency and small life of the products. This breakdown of the electrical products results in the loss of the owner. The increase in the electricity bill is also one of the consequences of this current fluctuation. Hence, the owner is in a double loss if they do not invest in a good quality voltage stabilizer or regulator. It is no longer a luxury but has become a need for every household or office that requires a long life of their Electrical products and less electricity consumption. So what are you waiting for? Grab your voltage stabilizer now from the dependable servo voltage stabilizer manufacturers in Jaipur, Rajasthan.

Benefits of Our Servo Stabilizer

Maximum load in industries consists of motors, heaters & compressors. At high voltage, they draw higher current, thus increasing the power Consumption & MDI and reducing the power factor. The servo voltage regulator / stabilizer is designed for 230 Volts (1-Ph), i.e., 400 Volts (3-Ph), and has maximum efficiency at this voltage. These heavy electrical equipment draws considerably more power at higher voltage, thus increasing the electricity bill of the industry. Similarly, in the case of bulbs & tubes, the percentage increase in power consumption will be more than double the percentage increase in voltage. The higher voltage also results in higher losses, causing the breakdown of Motors Lightings & all other electrical equipment.

The Servo stabilizer can save up to 15% on power consumption & reduction the breakdown of electrical equipment by up to 80% if the voltage supply is above the recommended voltage and higher efficiency of your equipment if the voltage supply is lower than the recommended voltage.

Input voltage variation % Reduction in Breakdown Possible Approximate Savings in Power Consumption
380 to 420 Volts Up to 10% Reduction Up to 5%
380 to 440 Volts Up to 20% Reduction Up to 7%
380 to 460 Volts Up to 60% Reduction Up to 10%
380 to 470 Volts Up to 80% Reduction Up to 15%

Advantages of Industrial Servo Voltage Regulator

  • 10 to 15 % saving in electricity bill ( More than 25 % on lighting load )
  • Up to 80 % reduction in the breakdown of electrical equipment.
  • Reduction in MDI by 10-15 %
  • Improvement in Power factor
  • Payback period within 6-12 months
  • Improved production of the industry.
  • Uniform Quality of the final product.


Effects of Voltage Unbalance

The main effect of voltage unbalance between phases is damage to the motor due to excessive heat. Voltage can create a current unbalance of 6 to 10 times the magnitude of voltage unbalance. Consequently, this current unbalance creates heat in the motor winding that breaks down motor insulation causing cumulative and permanent damage to the motor. The figure shows the percentage of temperature rise as related to voltage unbalance. The relationship is exponential & approximately increases by twice the square of the voltage unbalance.

To avoid frequent tripping of overload relays, the operator sets the relays at higher than the actual limits to continue production. Unfortunately, the motors cannot withstand this higher current for a long time, and in most cases, the motor burns out and damages controlling relays/contactors. The most suitable option is to use servo stabilizers with a separate control system on each phase (unbalanced type). It will take care of both unbalanced and balanced input supply providing a balanced 3-phase supply at the output.
