Main varieties of equipment
The market for electrical and power devices offers stabilizers in many different modifications.
The devices are divided into:
Each device has its own specific characteristics and shows the highest level of efficiency under certain conditions.
Style #1 is the relay version of the modules
Household relay devices are based on power relays which switch autotransformer windings. They have a wide control range and quickly compensate bursts of input voltage.
The models are equipped with an effective protection system protecting the internal components from possible short-circuits and overvoltages during the operation. Sold at an affordable price in all hardware stores or specialized supermarkets in all regions.
Compact size and light weight are the undeniable advantages of the relay stabilizers. Thanks to these qualities, they can be mounted not only on strong supporting walls, but also on weaker internal partitions and constructions
The disadvantages are the lack of power reserve, the low stabilization accuracy and the noise background in the form of clicks during the closing/opening of the contacts. The most important disadvantages are the short functioning time and the warranty of not more than 6-12 months.
View #2 - Advanced Inverter Units
The inverter stabilizer is one of the latest innovations in the electrical and power equipment market. It operates on the principle of pulse width modulation. Compared to traditional electronic and servo units, it supports a wider range of input voltages.
Has a comprehensive protection system that protects against all major network problems. Responds instantly to critical overloads that can take out equipment.
The highest input voltage accuracy is the most important feature of inverter units. In single-phase and three-phase models, it doesn't exceed 1% in household models and 0.5% in industrial models
The unit is not afraid of temperature or humidity fluctuations and works correctly in a wide temperature range. Due to the high costs, it has not yet become widespread even though it is considered one of the most efficient devices.
Look #3: electrodynamic technology
The electrodynamic (servo) products are operated correctly by an electric motor. It is controlled by a special electronic board with a microprocessor.
The units of this design continuously regulate the mains voltage and give a minimum error in stabilization.
Electrodynamic products are known for their high resistance to short/continuous overload and are suitable for difficult environmental conditions and low temperatures
The servo modules have a movable contact. If dust particles, dirt fragments or other foreign elements get on it, there is a great risk of sparking or spontaneous combustion. This severely limits the use of the devices and categorically forbids their installation in rooms with gas equipment.
The disadvantages of electrodynamic modules are the impressive weight and large dimensions, the poor performance in case of network fluctuations, the need for regular professional maintenance and the short operating time.
View #4 - Electronic type devices
Electronic (\"semistors\" or \"thyristors\") devices refer to precise and highly efficient technology. They contain no mechanical elements involved in automatic voltage regulation. The operation of the semiconductors controlling the autotransformer is controlled by an internal microprocessor.
Electronic type devices from reputable brands do not make noise during operation. A slight buzzing noise may occur only with severe overloads or with insufficient working capacity
The main advantages of electronic units include fast and clear response to mains voltage surges, minimal stabilization error and high operating efficiency.
Makers equip the units with a multi-level protection system that protects all operating nodes from common mains faults and problems. Electronic stabilizer housings are compact and can be mounted on both load-bearing walls and lightweight interior partitions.
Disadvantages of the models include high initial cost, costly repair in case of failure and sensitivity to sudden mains overloads.
View #5 - hybrid devices
Hybrid stabilizer is another modern novelty that first entered the market in 2012. It differs from the traditional relay module by additional relay converters incorporated into the design.
Hybrid type devices feature a compact housing and smoothly equalize the voltage. In continuous mode, they provide an even power supply and reliable protection against power surges
In operation, they create a noticeable sound background and are sold at a high price.

Area recommendations for buyers
The right voltage regulator ensures the correct operation of all the electrical appliances in the house and protects the household appliances from burning out and breakdown due to power surges or short circuits.
If mains voltage fluctuations are very rare and in small ranges and there are no devices and systems in the house that require high quality and stable power supply, there is no need to spend extra money and pay for an inverter or electronic module.
When purchasing a relay, you should remember that during operation it creates a noticeable noise background. Therefore you should consider beforehand where to place the unit so that it does not interfere with a comfortable rest and proper sleep
A reliable and inexpensive relay stabilizer will do an excellent job of voltage equalization. If you want to protect computers and other sensitive equipment from voltage fluctuations, you should give preference to electronic modules. These units will protect the gadgets from burning out and extend their life.
Buy an inverter device only if there are significant constant drops in the network. In other cases such financial expenses are not reasonable. The rules for selecting a voltage regulator for the refrigerator as well as for the gas boiler can be found in our recommended articles.
Power and phase parameters
Power parameters should be treated with special attention. You must not buy the unit with \"too much\", otherwise it will always be worn out and will not tolerate the connection of new power consumers. It is better to buy a module with some reserve, thereby prolonging the term of its normal operation.
The capacity of stabilizers for single-phase electrical network varies in the range from 0.1 to 135 kVA, for three-phase - from 2 to 6000 kVA. For a small house with a minimum of household appliances are suitable 500-1500V devices. In spacious cottages, single-phase units from 2000 V or three-phase units from 2-3 kVA are installed.
If irrigation systems and other consumers of large amounts of energy resources are connected to the network, strong and robust stabilizers with a good power reserve are required. This will ensure proper operation of all units and protect the utilities from overheating.
Three-phase stabilizers consist of three separate modules per phase. They are all in the same enclosure and are controlled by a single control board. When a phase dip or phase reversal occurs in the mains, the control unit completely disconnects the unit from power
All voltage regulators are divided into single-phase and three-phase. In older homes located within the city, most often there are single-phase electrical networks with a current voltage of 220 V.
These require a single-phase stabilizer of any kind. The model is selected according to the individual requirements and the number of household appliances present in the room.
Country cottages, homesteads and country houses are most often connected to a three-phase network of 380 V. A three-phase sturdy unit is ideal for such conditions. It evenly distributes the current load and effectively protects the communication elements from overvoltage.
How important is stabilization accuracy?
Stabilization accuracy is the amount of deviation of the output value of the line voltage from the fixed value. The lower the percentage, the better.
In the budget range the error between the values ranges from 5% to 8%. This is considered the norm for household household networks that do not have capricious technical appliances with high demands on the quality of energy supply.
Stabilizers with a deviation level less than 5% are more expensive than similar devices with a higher index. It is only worth overpaying for them if there is a real need
For sensitive equipment and complex systems, devices where the deviation level does not exceed 1-2% are usually used.
Place and brand
Do not buy a nameless product from a questionable market seller. It makes more sense to go to a specialized store or supermarket that offers a wide range of products and strictly follows the rules for storing electrical equipment.
Inexpensive voltage regulators with an efficiency level of 80-93% will be perfect for standard household needs. If you have many devices, systems and sensitive equipment connected to the network, it makes sense to spend money on an expensive unit giving 94-97% efficiency
The branded device will cost a bit more, but this expenditure is quite justified by the reliable and long-lasting operation. In addition, the official representative of the manufacturer will certainly issue a warranty card for maintenance and repair in a certified service center.
Only by studying all the tips and clearly understanding how to choose exactly the right type of voltage stabilizer for a private home, you can correctly purchase the necessary equipment.
