Servo Voltage Stabilizer

What is Servo Voltage Stabilizer? 

A Servo Stabilizer is a stabilization system controlled by a servo motor that uses a Buck-Boost transformer booster to catch input voltage changes and adjust current according to the desired output.

The output voltage of an AC synchronous motor is controlled by components such as a control card, dimmer, comparator, transistors, and mocs, among others.

This sort of stabilizer is helpful for ensuring a precise output voltage. When the input voltage changes by up to ±50%, it outputs a voltage of ±1%. This kind can handle loads up to 5000 KVA and beyond.

Servo Stabilizers are a popular substitute for low-high rating appliances that give unmatched voltage supply to protect your delicate equipment in commercial and domestic settings, residences, and businesses.
 

How Does A Voltage Stabilizer Work?

A Voltage Stabilizer's primary job is to perform two essential tasks: Buck and Boost. Buck and Boost functions are more than a means to maintain a consistent voltage in high or low voltage conditions.

Let us break it down into parts to make it easier to understand.
 

 1. Buck Function- (Method- Applied Voltage to the load = Primary Coil Voltage - Secondary Coil Voltage)

A switching circuit is built into the Voltage Stabilizer. Switches/ Relays are used to manually or automatically switch the Load connection to the 'Buck' mode configuration when the primary supply detects an overvoltage.
 

2. Boost Function- (Method- Applied Voltage to the load = Primary Coil Voltage + Secondary Coil Voltage)

Primary and secondary coil voltages are added together and applied to the load when using the boost function of a transformer's secondary coil.

A two-stage voltage stabilizer uses Relay 1 and Relay 2 to offer Buck and Boost configurations when the voltage is fluctuating, i.e. For example, if the AC input voltage is 230 volts AC and the output voltage is also 230 volts AC, then the output voltage must be 230 volts AC as well.
 

Types of Voltage Stabilizers

Stabilizers with power electronic control circuits, continuous voltage correction stabilizers, and switchable voltage stabilizers may all be classified into one of three categories:

1. a. Servo Controlled Voltage stabilizers
2. b. Relay-type Voltage Stabilizers
3. c. Static Voltage Stabilizers 

Let’s understand it more deeply:
 

1. Servo Controlled Voltage Stabilizers

Voltage stabilizers operated by a servo motor are also known as servo stabilizers. Essential components of these stabilizers include a servo motor and buck-boost transformer, an autotransformer, control circuitry, and a motor driver.

If a voltage fluctuation is detected, an electronic control circuit moves an arm on a transformer to correct it.

With this, you can ensure that voltage across the secondary of your buck-boost transformer is exactly what you want.
 

2. Relay-Type Voltage Stabilizers 

There are a lot of electromagnetic relays in a relay-type voltage stabilizer linked to the transformer tap. They turned on one at a time to keep the output voltage stable. Accurate voltage stabilization is not achievable with relay-type stabilizers.
 

3. Static Voltage Stabilizers 

When it comes to servo stabilizers, a static voltage stabilizer does not contain any moving parts, as its name suggests. Using these Static Voltage Stabilizers, the voltage correction may be made to within 1% of its original value. This static voltage stabilizer includes a 'Buck & Boost Transformer', a Microcontroller, a Microprocessor, and other vital components.
 

Technical Guide To Select Servo Voltage Stabilizer

1. Single Phase or Three Phases

Selecting a single phrase or three-phase servo stabilizer is your first step. Your connection to the electrical grid may aid this selection. Choose a 1-phase voltage controller if you have a 1-phase grid connection, whereas a 3-phase voltage stabilizer is the best option if your grid is 3-phase.
 

2. Input Voltage Range

These servo stabilizers must operate within specific input voltage ranges, as here is where the real magic happens. Standard voltage ranges are 340 – 480 V AC, 300 – 460 V AC, 240 – 480 V AC, and 190 – 480 V AC, for example. 
 

3. Mounting

Make sure the stabilizer you're considering can be wall-mounted before moving on to the following stage. Because it is powered by electricity, the equipment is more susceptible to harm if it is left out in the rain or snow.
 

4. KVA Rating of Servo Stabilizer

Determine the size of the servo voltage stabilizer that you need. After you have turned on your entire load, you may measure your overall amp draw.
 

5. The Output Voltage

If you have any questions, please don't hesitate to ask a professional. The voltage needs of your equipment should be examined before making a stabilizer selection. Some devices require 380 volts, while others call for 400 or 415 volts.
 

Top 10 Benefits and Usage of Servo Voltage Stabilizer

1. Protects Industries from Damages

A servo voltage stabilizer is an essential tool for any company that uses a wide range of electrical appliances and equipment. So even a slight change in voltage may significantly impact all of the gadgets and, thus, human life.
 

2. Less Power Consumption

When it comes to conveying power, it does so at an appropriate level rather than causing damage by overloading the device with too much power.
 

3. Prevents Equipment Breakdown:

This device failure might cost you twice as much. However, using a Servo voltage stabilizer might help to avoid this situation.
 

4.The Savior of the House

Electrical equipment is utilized in the household as well as in the workplace. Security precautions must be taken at home for the safety of family members. It not only safeguards your loved ones from the dangers of voltage, but it also saves you money in the long run.
 

5. Low Maintenance Cost

A Servo voltage stabilizer features a strong motor that requires less maintenance, allowing you to save money on your electricity bill. Not only does it save money on additional costs, but it also assures a smooth manufacturing process that increases profits.
 

6. Reduction in Power Bill

Servo voltage stabilizer gadgets control the power supply to the devices, resulting in a lower power bill due to this controlled supply. Indeed, it's a smart strategy to use in your own house.
 

7. Highly Resistant

Even in the worst-case scenario, a Servo voltage stabilizer can function similarly. Such sturdiness considerably reduces the risk of voltage variations and the accompanying risks.
 

8. Intuitive Machine Operation

When using a servo voltage stabilizer, it is pretty simple to shift the stabilizer mechanism at any moment. A lot of necessary time is saved by industries as a result of this.
 

9. Exceptionally Well-Informed

Using a servo voltage stabilizer, whether at home or in the workplace, is very clever since it saves a lot of money in the long run, including the cost of new equipment, the cost of repairs, the cost of electricity, and so on.
 

10. Customization is a Breeze

Servo voltage stabilizers come in various strengths and voltage rates, which may be easily customized. Furthermore, its motor can be simply replaced if it malfunctions or fails.
