Voltage stabilizers: TOP - 25 popular models

Most of the apartments are equipped with various and sophisticated appliances. A sudden interruption of light can significantly affect the operation of the devices, as well as hit the owner's budget. The editors of the site "bestx.htgetrid.com/en/" have prepared for you an overview of popular stabilizers for 2020.

What is stabilizer

A stabilizer is an electrical device, the main function of which is to eliminate sudden voltage surges when the output current changes, without negatively affecting the operation of electronic equipment. It also removes high frequency interference from the voltage.

Types of stabilizers

Both online and offline electrical stores provide a wide selection of Russian and foreign stabilizers, focusing on the needs of users. There are many types of such devices, so we will consider them in more detail.

By device type

Any stabilizer, regardless of power and cost, is made according to a standard scheme, which is based on a specific rule for stabilizing electricity. There are 6 topologies:

1. Ferroresonant.
2. Relay.
3. Thyristor.
4. Electromechanical.
5. Hybrid.
6. Inverter.

All types of stabilizers have pros and cons, which are explained by their design features. The key characteristics of stabilizers of any kind require careful consideration, since it is in their indicators that the effectiveness of the functioning of a particular device model with modern equipment lies.

Ferroresonant

These are the first devices that are in high demand in Russia. The peak of the popularity of such stabilizers falls on the 50-60s. 20th century, due to the emergence of tube-type TVs and other household appliances that needed protection from power surges.

Ferroresonant devices differ with most of the new stabilizers in the simplicity of the electronic circuit, as well as the lack of an automatic transformer. They reduce or increase the voltage indicators due to the ferroresonant effect - the magnetic-electrical interconnection of two chokes, one of which has a saturated core (output), and the other unsaturated (input).

Advantages:

Disadvantages:

The mentioned disadvantages are typical, first of all, of traditional devices of this type of the first generations. In devices of the modern generation, they are minimized or completely devoid of most of the above disadvantages.

Relay

Stabilizers of this type are classified as electronic devices, the principle of operation of which is based on intermittent (sequential) stabilization of electrical energy.

This stabilization principle consists in switching transformer windings in automatic mode with the choice of the one whose voltage is extremely close to the nominal one.

The switching of the circuits required to increase or decrease the current at the input is carried out by turning on electronic-type power relays (which is why such stabilizers are called relay).

Advantages:

Disadvantages:

Devices of this type will be an excellent solution in order to protect low-power equipment in networks, which are typical for minor current fluctuations in the mains. The aforementioned disadvantages indicate the incomplete compliance of the models in this category with respect to the requirements for the protection of innovative electronics, which are famous for their increased sensitivity to even minor drops.

Thyristor

These models can be considered the result of changes and improvements in the discrete stabilization method. Their design features and principle of operation are similar to relay-type devices.

The main difference is that the switching of the automatic transformer windings is carried out not by relays, but by semiconductor electric power switches - thyristors, which increase the stabilization accuracy and make the operation of such models almost noiseless.

Advantages:

Disadvantages:

Electromechanical

Devices of this type saw the light almost at the same time as ferroresonant stabilizers, but electromechanical ones differ from them in design features and the principle of operation.

The main components of any device of this type are an automatic transformer and a moving current-collecting contact, which is made in the form factor of a roller, brush or slider.

The said contact moves along the transformer winding, as a result of which a smooth increase or decrease in the transformation index and proper transformation (correction) of the one coming from the power grid is carried out.

Advantages:

Disadvantages:

The aforementioned disadvantages explain the truncated area of ​​use of devices of this type, but they are still in demand in networks without sudden current surges.

Hybrid

This type of stabilizer came out in 2012. This is an electromechanical type device, the design features of which include 2 relay rectifiers. The main module is an electromechanical device.

Relay modules are activated at the moment when electromechanical units cannot provide 220 V. This usually happens if the incoming voltage is too weak, or, on the contrary, is high enough.

The electromechanical device operates in a spectrum that varies between 144-256 V, and the relay modules begin to operate when the value drops to 144 V or, if increased, more than 256 V.

Important! The limiting spectrum ranges from 105 to 280 V.

Hybrid models will be an excellent solution for uninterrupted supply of electricity to apartments, private houses, office premises or shopping centers.

Advantages:

Disadvantages:

Inverter

This is a "fresh" topology of stabilizers, mass production of which was launched in the late 2000s. Modern design features and parameters that surpass the above types of devices make these models a real breakthrough in power stabilization.

The essence of operation of these devices is very similar to on-line uninterruptible power supplies, since the principle of operation of these devices is based on the modern technology of double energy change.

At first, the converter transforms the incoming alternating current into direct current, which then accumulates in the preliminary capacitors and goes to the inverter, which performs the opposite transformation into an alternating stabilized current at the output.

Advantages:

Disadvantages:

Other typologies of stabilizers

Stabilizers are also divided by:

• type of input voltage - single-phase (220 V) or three-phase (320 V);
• placement method - wall, floor, rack, universal and rack-mount;
• method of connection - via terminals or by means of a Euro socket.

What to look for when buying

In order to prevent elementary mistakes when choosing, before buying a stabilizer, you should pay attention to the following criteria:

• maximum active power;
• cooling method;
• input operating voltage range;
• stabilization accuracy percentage - the lower the better;
• speed reaction;
• tips and advice on choosing from experts.

Before going to the store, you should calculate the total consumption of all electronic devices, and then add 20% to the resulting value. This is done to ensure that the stabilizer operates at its nominal value.

It is also necessary to look at the functionality, take into account maintainability and customer reviews on the Internet. Only after that you can go to the store and choose equipment, focusing on the price and the specified characteristics.
