Today, each of us at home has equipment that is sensitive to stability and signal quality. These are refrigerators, computers, televisions, microwave ovens and much more. If you conduct a brief analysis of the quality of electrical networks, you can draw certain conclusions. And it’s not even necessary to be a specialist. Here, and so it is clear, the nominal deviation from 220V is more than acceptable. And admissible, we note, is only plus / minus 10V. That is 210-230V. Let's talk with you about how to choose a 220V voltage regulator for your home and protect your equipment from breakage.
General information
As noted above, the quality of the power grid is really not happy. But all would be fine in good weather, when the voltage at the outlet is more or less stable. The most miracles begin in a strong wind. Then there is a chance to observe the voltage of both 150V and 280V. All this can lead to the fact that your refrigerator, TV and other expensive equipment will burn out.
To avoid this, it is necessary to use a voltage stabilizer. This is not such an expensive technique, but very necessary in our time. Any surge in electricity in the network will be stabilized. The worst thing that can happen is that the stabilizer fuse will burn, which costs no more than a few rubles. Agree, not the biggest loss.
The need for a stabilizer
It is worth noting that the voltage regulator 220V for the home is not so difficult to choose. It is quite another thing that many are not going to do this. To understand whether you need such an acquisition or not, you do not need to think long. But to go blindly and buy a stabilizer is also not worth it.
To dot all the "i", it is necessary to take measurements. For this, special measuring equipment is used, which allows you to record the maximum and minimum power surges. So, if in general the network was stable, and the voltage did not go beyond 205-235 V, then the stabilizer is not vital. Although it is necessary to protect expensive and sensitive to differences equipment, and this is a fact. If the measurements showed deviations of more than 10% in one direction or another, then you need to install protective equipment. Otherwise, any electronic device, whether it is a TV or a refrigerator, may fail. Believe me, repairs will be very expensive. Sometimes it’s even more advisable to buy new equipment than to repair an old one.
Single phase or three phase?
It is difficult to say exactly why the questions arise in this case. If a single-phase voltage is used in your room, and all household appliances are single-phase, then the stabilizer should be appropriate. Three-phase network is often used in factories or in offices. It is usually powered by electric motors, powerful air conditioners or pumps. In this case, only 3-phase stabilizer is permissible.
But it often happens that a 3-phase network is suitable for the house, and all the devices used are single-phase. Which voltage regulator 220V to choose in this case, you ask. There are some opportunities for optimization. If each phase is loaded equally, then we install 3 single-phase stabilizers with equal power. If important household appliances are connected to one or two phases, then protective equipment is installed on them, and the last line can be connected directly.
What voltage regulator 220V to choose for giving
One of the most important points is the power of protective equipment. In order to choose the right stabilizer, it is necessary to correctly calculate the total load of the electrical appliances that will be connected to it. Each electronic device has a technical passport, power consumption is indicated there . But do not forget about such an important parameter as starting power. For example, a household refrigerator has a power of 0.2 kW. Moreover, its multiplicity according to the passport is 5. It is necessary to multiply 0.2x5, and we will get the starting power, which in our case is 1 kW. Of course, sometimes we do not use several household appliances at once. In this case, the total load on the equipment will be an order of magnitude less. It is not recommended to overload the stabilizer, since the protection will work, and it will not turn on until you disconnect one of the household appliances.
Always buy with a margin of power
It is impractical to buy equipment back to back. For example, you do not know when it becomes necessary to connect new equipment to the stabilizer. Imagine that the network is 250V, and you urgently need to run a report on the work on the computer. But the stabilizer is busy with other equipment that cannot be turned off. Power is also not enough. The situation is stalemate. For this simple reason, always take protective equipment with a power reserve of 20-30%.
Another important detail - the lower the voltage in the network, the lower the power of the stabilizer. For example, Shtil's 7kW protective equipment can withstand heavy loads. But the specific power, in our case it is 7 kW, is taken at the optimal voltage in the network 220V. If this indicator drops to 150V, then the power will drop to 4.8 kW. In principle, we got acquainted with the main parameters, now let's quickly go through the popular manufacturers.
220V voltage stabilizer for the house "Calm"
The company "Calm" produces a wide range of protective equipment. A variety of stabilizers are offered, ranging from low-power household to expensive office models. This domestic manufacturer has several undeniable advantages. Firstly, the affordable cost of equipment. When compared with European models, the savings are about 10%.
The Calm R 110 model is used at a voltage range of 165-265V in the network. At the same time, this unit boasts plus / minus 7% stabilization. This is hardly suitable for sensitive electronic equipment. The price of such an aggregate is only 2,900 rubles. But the R 16000 with a power of 16 kVA gives a stabilization of +/- 4%, which is already suitable for complex sensitive equipment. But such an assembly costs 70,000 rubles. It is advisable to install it in offices where there is a high total load on the network. In general, it is a great manufacturer. The build quality of the equipment is high, and at the same time its cost is quite affordable.
Products of the company "Energy"
You probably noticed that most attention is paid to the domestic manufacturer. The fact is that such equipment is in high demand for several reasons. The first is affordable cost, and the second is ease of maintenance and repair. Believe me, in case of any breakdown, it is much easier to find spare parts for the "Calm" or "Energy" stabilizer than for the European model.
As for this particular manufacturer, many consumers leave positive feedback. For example, a 220V voltage stabilizer for the Energy house SNVT-500/1 is in demand. This is 0.5 kVA protective equipment. Such a stabilizer is made specifically for connection to gas equipment. Most 2-circuit boilers have a huge amount of accurate and sensitive electronics, which does not like even the slightest voltage drop. This unit is able to stabilize the voltage up to +/- 3%. All this for 2 900 rubles. The company also offers more powerful models, such as ARS-1000, 1,500 and others. Pick up equipment depending on power, and everything will be all right.
What do consumers say?
Now you already know how to choose the right 220V voltage regulator for your home. Which is better is definitely hard to say. For example, for small loads and connecting accurate sensitive electronics, the Energy technique is excellent. If the load on the protective equipment is significant, but stabilization deviations within 8% are acceptable, then you can safely give preference to the "Calm" technique. Fortunately, today there is a choice, and quite a lot. If you do not trust the domestic manufacturer, then there are plenty of European stabilizers in our market. Most of them, especially German, Italian, etc., are very high quality. But often there are problems with timely repairs, since spare parts are often delivered to order, and this is not too fast.
Conclusion
Here we come to the end of our article. During this time, we managed to figure out how to choose the right 220V voltage regulator for the home. The wall-mounted accommodation option, by the way, is very convenient. This is indicated by many consumers. The unit is mounted on the wall using fasteners and does not take up space in the room. The rest, where such equipment will be located, does not matter. Of course, we are now talking about houses and apartments, not offices and industrial buildings, where the weight of the stabilizer can exceed 100 kilograms. In general, this is all that can be told on this topic. Calculate the total load, determine the manufacturer and make a purchase. Only in this way you can reliably protect your electronics from damage due to surges in electricity in the network.
