Voltage Stabilizer

CtrlTech automatic voltage stabilizer

Voltage stabilisers aid with voltage stabilisation. This implies that it automatically adapts to the correct range if the supplied voltage varies or fluctuates.

This is accomplished through the use of an auto transformer in conjunction with electromechanical relays.

Numerous Sorts of Power Issues

There are two types of power problems:

Issues or disruptions that arise when a mains

supply is used. Here, we are concerned with issues of power quality.

When the mains power supply is completely cut off. Here, we're concerned with system availability and business continuity.

Power supply issues can be attributed to a variety of factors, including distribution network failures, system switching, adverse weather and environmental conditions, large plant and equipment, or simply faulty hardware. Regardless of the cause of the problem, one or more of the following types of power problems will result:


Are brief drops in the mains supply voltage that typically last several cycles. They are a rather common type of disturbance. Sags can cause sensitive equipment to lock up or hang, resulting in data loss and system resets.


Are brief increases in the voltage supplied by the mains that typically last several cycles. Surges can cause equipment to fail prematurely. The high voltage results in component wear and degradation. This may not be apparent until the system fails, though heat dissipation is a good sign.

Spikes and Transients:

These are extremely brief bursts of strong energy lasting barely a few milliseconds. When transients or spikes occur, equipment may become locked or hang, crash, or even sustain damage, resulting in data loss and corruption. Large transients can occur as a result of localised or, in the worst-case scenario, direct lightning strikes.

Electrical Vibration:

This is a type of high frequency noise that can occur in either the common or normal mode and can cause significant disruption and damage to circuits and equipment.


Are prolonged dips in the mains power supply voltage that can last many days. Equipment may reset or even stop completely during a brownout.

Blackouts and Failures of the Mains:

When the mains electricity supply is totally cut off, this is referred to as a total mains failure or blackout. A brief interruption in the mains supply can cause many of the components that comprise a typical data or speech processing IP network to crash, lock, or reset, including the PC, terminal, console, server, PBX, printer, modem, hub, or router.

A survey can be conducted to ascertain the nature, duration, and magnitude of power difficulties encountered at a particular location.

Voltage Stabilizers

Voltage Stabilisers are used to guard against voltage fluctuations in machinery and electrical equipment. This guarantees that they operate at a steady voltage and maintain the power supply's quality. The devices are extremely simple and intuitive to operate; we offer three different types of voltage stabilisers in our range, all of which include a digital display for control purposes:

Servo Motor Stabilizers : These sorts of voltage stabilisers are more frequently employed in industry. On the one hand, they are incredibly precise and rugged, making them suitable for a wide variety of applications. There are numerous servomotor types available for this product range. Contact our technical support team for assistance in determining the best appropriate device for your project.

Static Stabilisers are also extremely precise devices that are defined by their response time to voltage changes. Additionally, they are available in single-phase or three-phase configurations.

Relays Stabilizers: This version was created specifically for personal use. They are utilised in situations where high precision is not required but the voltage must constantly remain within a specified range. Additionally, this type of voltage stabiliser is the least expensive.

Selection Guide for Voltage Stabilizer

Verify the device's voltage, current, and power rating. It is indicated on the specification sticker located near the power socket; alternatively, consult the user handbook.

The standard service voltage in India is 230VAC, 50 Hz.

To determine the maximum power output, multiply "230 x Max rated Current" by the total current rating of all equipment that will be connected to the stabiliser. Stabilizer ratings are calculated by adding a 20-25 percent safety margin. If you intend to add other devices in the future, you can preserve a buffer for them.

Additionally, you should consider the surge current that flows when the device is turned on.

If the Voltage Stabilizer's rating is also expressed in watts, use a power factor of 0.8 (W=V*A*pf).

The most critical aspect is to understand the nature of the load attached to the stabiliser. To begin, you must record the power (or wattage) consumption of all equipment that will be connected to the stabiliser. The sum of the power consumption (or Watts) and the load on the stabiliser in watts will give you the load on the stabiliser in watts. However, the majority of stabilisers are rated in VA (Volt Ampere) or kVA (kilo Volt Ampere which is equal to 1000 Volt Ampere). Although you will need to perform some measurements to convert Watts (W) to VA (or Volt Ampere), you can raise the Watts number by 20% to obtain the estimated VA size that you may require.

Thus, if the total wattage connected to your stabiliser is 1000, you can choose between a 1200 VA or 1.2 kVA stabiliser. (Please note that 20% is suited for household systems and may not be suitable for industrial systems with a low power factor.)

Typically, stabilisers are available in a variety of operating ranges (the operating range refers to the voltage range over which the stabiliser operates/stabilizes the input utility voltage and produces a desired output voltage). It is critical to select a stabiliser that is compatible with the voltage fluctuations in your area.

Make a note of the magnitude of power fluctuations that occur frequently in your area. (For example, extremely low/high voltage zones, intermediate high/low voltage zones, and so forth.) You must select the operating range of your stabilisers according on the demands of your area. For example, if your area sees exceptionally low/high voltage swings, you may need to choose a stabiliser with a wide operating range.

Voltage Stabilizer FAQs

Voltage stabilizer, as the name implies, aid in voltage stabilisation. This means that if the supply voltage varies or fluctuates, it automatically adjusts to the correct range.

It accomplishes this through the use of a combination of an auto transformer and electromechanical relays.

A voltage stabiliser for television ensures that voltage surges do not damage your expensive television and regulates safe power output to ensure its continued protection. When lights, fans, and other electrical devices are operated at low voltage, the performance and life of the equipment are reduced.

Even if the input voltage is either too high or too low, the stabilizer will provide a stable and safe voltage to the connected equipment within the prescribed limit. It accomplishes this through te use of an auto transformer with multiple tapings that are selected as primary/secondary for step up/step down operations based on the input voltage level. The tapping selection is accomplished by arranging relays in the suitable configuration.

Contrary to popular belief, this is not required. Due to the fact that stabilisers already include a low and a high cut-off feature, they will automatically power down connected equipment during voltage variations.

It is advised that you use the LCD TV Stabilizer to protect and optimise the performance of your LCD TV. LCD / LED televisions are more vulnerable than CRT televisions to voltage fluctuations and spikes. LCD / LED televisions operate at voltages ranging from 90V to 290V. This illustrates that some televisions are more sensitive to high voltages than others.

Yes, a stabiliser is required regardless of the model. There is no stabiliser in the refrigerator. Manufacturers of refrigerators state that their devices are capable of operating at both low and high voltages. However, operating the refrigerator at a low voltage affects the cooling efficiency and longevity of the refrigerator. Additionally, the refrigerator is deficient in terms of low- and high-voltage cut-offs. This is why major refrigerator manufacturers specify on their warranty cards the use of a high-quality voltage stabiliser.

To guarantee that electrical systems operate effectively, it is vital to ensure that the power they receive is of sufficient quality to avoid performance degradation or system life expectancy reduction. Without adequate power, an electrical equipment or load may malfunction, fail prematurely, or cease to function entirely. There are numerous ways in which electric power might be substandard and numerous reasons for such substandard power.

The most frequently asked question is what the difference is between a Voltage Stabilizer and an AC Power Conditioner. Both protect against voltage transients, spikes, sags, and brownouts, but an AC Power Conditioner also protects against Electrical Noise and provides a higher level of protection against transients and spikes. Generally, an AC Power Conditioner (Power - Line Conditioner) is nothing more than a Voltage Stabilizer with an isolation transformer integrated. When a satisfactory solution for each cannot be provided, 'Common Mode' noise (E to L and E to N) can become an issue. This interference is suppressed to safe levels when a shielded isolating transformer is included in a Power Conditioner. A clean supply is a term that is frequently used to refer to the output of an AC Power Conditioner. As expected, an AC Power Conditioner is typically more expensive than a Voltage Stabilizer/Regulator.

Disconnect the stabiliser from the mains board and use a multimeter to check the input / incoming voltage in the mains socket. If the voltage is between 180 and 240 volts, it is acceptable. Now, bypass the stabiliser and connect AC directly to the mains supply for the sole purpose of checking for serviceability; I hope this works.

Thus, leaving it on 24 hours a day can result in significant electricity consumption. This is why, rather than using a mainline stabiliser, we recommend using a voltage stabiliser for individual appliances. A mainline stabiliser must operate 24 hours a day, 365 days a year, resulting in increased electricity bills.

Servo stabilisers are a necessary component of any manufacturing operation that makes use of electrical appliances and machinery. With servo stabilisers in place, expensive machinery is protected from voltage fluctuations and excessive electrical consumption is reduced. To help you have a better knowledge of the subject, we're going to look at the operation of a servo voltage stabiliser today.

Servo stabilisers, in comparison to typical transformers, use a "Servo-mechanism" to control incoming voltage and regulate it to the specified voltage for an appliance.

Printing Machines: Servo Stabilizers are a must-have for the printing industry and machinery such as flexographic machines, offset lithography, flexography, digital printing inkjet, and xerography, among others. A minor difference in voltage can wreck havoc on printed material.

CNC Machines: CNC machines, as well as any imported machinery, must be safeguarded against voltage or power concerns, as they contain extremely sensitive circuits that are tuned to a precise output voltage that can only be ensured by a high-quality servo stabiliser. At times, we may even require a Step Up or Step Down Isolation Transformer to ensure that the machine receives the power it requires.

Medical Equipment: As you are aware, medical equipment is quite an expensive purchase and their use is highly exclusive, we need to protect equipment such as MRI machines and CT scan machines, digital X-ray machines, and so on from various types of voltage problems such as fluctuation, spikes, and so on. The best course of action is to contact the most reputable servo voltage stabiliser manufacturer in your area and arrange for installation.

Textile Machines: The textile sector is the backbone of the Indian economy, and the Indian government supports and promotes textile manufacturing firms that rely on imported embroidery machines, knitting machines, and tufting machines. By giving stable voltages to these devices, our servo stabilisers and isolation transformers ensure their ultimate safety. JUKI India was previously a provider of these machines and relies on purevolt's top servo stabilisers for their juki machines.

Packaging Machines: The packaging industry has advanced significantly over the last few years; formerly, there were numerous manual processes involved in packaging specific products. Now that packing factories have been automated as a result of investment in cutting-edge technology and rapid innovation, each country has its own set of voltage issues, which is why automatic voltage controllers provided by purevolt are the ideal option.

Plants / Factories: Nowadays, industrialists running factories and industries understand the value of Servo Voltage Stabilizers and Voltage Controllers, and as a result, they budget for Servo Voltage Stabilizers during the first stages of factory planning. Not only did these voltage regulators assist them in reaching a high power factor, they also offered them with benefits such as minimal failures of expensive machinery and tools, a reduction in MDI, and energy savings.


Servo Voltage Stabilizers with air cooling are extremely beneficial for a variety of electrical and electronic applications.

The servo stabilisation mechanism, combined with air cooling, effectively maintains optimal voltages.

This stabiliser consists of a transformer and a power control circuit for regulating the output alternating current voltage. The negative feedback circuit automatically regulates the voltage or current and maintains it at a predetermined or required level. The most effective feature is that the voltage regulator operates completely automatically during its operation.

OIL-COOLED SERVO VOLTAGE STABILIZERS: - Oil-cooled stabilisers have a larger capacity for short-term or persistent overload than air-cooled stabilisers. The primary distinction between oil- and air-cooled stabilisers is that oil-cooled stabilisers have a greater capacity. These are utilised in locations where the power source has a high frequency of fluctuating voltage. An oil-cooled stabiliser ensures that power supply fluctuations do not harm electronic or electrical equipment.

Outdoor servo-controlled voltage stabilisers are used to provide a consistent voltage and current to a load. They offer uninterrupted power even when the input is subjected to significant variances and changes. These Servo Controlled Voltage Stabilizers are great for completely protecting expensive electrical equipment or machines from under or over voltage. These outdoor servo voltage stabilisers have an error amplifier to eliminate voltage errors. They ensured decreased distortion in the output waveforms due to their simple design and operation.

Additionally, it is referred to as waterproof stabiliser. It is a stabiliser enclosed in a weatherproof cabinet to protect it from moisture and dust. Used in remote applications such as telecommunications, traffic signalling, oilfields, and broadcast stations, among others.
