Stabilizer voltage 220V for the house: which is better?

Today, each of us at home has a device that is sensitive to stability and quality of electrical signal. These are refrigerators, computers, televisions, microwave ovens and much more. If we make a brief analysis of the quality of electrical networks, we can draw certain conclusions. And it is not even necessary to be an expert. Here and so it is clear, the nominal deviation from 220V is more than permissible. And the permissible, we will note, is only plus / minus 10V. That is 210-230V. Let's talk with you about how to choose a voltage regulator 220V for your home and protect your equipment from breakage.

General information

As noted above, the quality of power grids is really not encouraging. But all would be fine in good weather, when the voltage in the outlet is more or less stable. The most miracles begin in a strong wind. Then there is a chance to observe the voltage and 150V and 280V. All this can lead to the fact that you will burn the refrigerator, TV and other expensive equipment.

To avoid this, it is necessary to use a voltage regulator. This is not such an expensive technique, but very necessary in our time. Any power surge in the network will be stabilized. The worst thing that can happen is a fuse of the stabilizer that costs not 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 home is not so difficult to pick up. It is quite another matter 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 blindly go and buy a stabilizer is also not worth it.

To arrange all the points above the "i", it is necessary to make measurements. For this purpose, special measuring equipment is used, which allows recording the maximum and minimum power surges. So, if in general the network was stable, and the voltage did not go beyond the 205-235 V mark, then the stabilizer is not vital. Although it is necessary to protect expensive and sensitive equipment, this is a fact. If the measurements show deviations of more than 10% in either direction, then you need to install protective equipment. Otherwise, any electronic device, be it a TV or a refrigerator, can fail. Believe me, repairs will be very expensive. Sometimes it is even more expedient to buy new equipment, rather than repair the old one.

Single-phase or three-phase?

It is difficult to say why questions arise in this case. If you use single-phase voltage in the room and all household appliances are single-phase, then the stabilizer should be appropriate. A three-phase network is more often used in production or in offices. It is usually powered by electric motors, powerful air conditioners or pumps. In this case, only the 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 to choose from 220V in this case, you ask. There are small 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 they are put on protective equipment, and the last line can be connected directly.

What kind of voltage regulator should I choose for a dacha?

One of the most important moments is the power of protective equipment. In order to correctly choose a stabilizer, it is necessary to correctly calculate the total load of electrical appliances that will be connected to it. Each electronic device has a technical passport, it indicates the power consumption. But do not forget about such an important parameter as the starting capacity. For example, a household refrigerator has a power of 0.2 kW. At the same time, its multiplicity by the passport is equal to 5. It is necessary to multiply 0.2x5, and we will get the starting capacity, 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 smaller. It is not recommended to overload the stabilizer, as protection will work, and it will not turn on until you disconnect one of the household appliances.

Always buy with a reserve of power

It is not advisable to buy equipment end-to-end. For example, you do not know when it will be necessary to connect new equipment to the stabilizer. Imagine that the network 250V, and you urgently need to run a report on the work on the computer. But the stabilizer is occupied by other equipment, which can not be turned off. Power is also not enough. The situation turns pathetic. It is for this simple reason that you 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, the protective equipment of the company "Shtil" at 7 kW can withstand heavy loads. But the specific power, in our case is 7 kW, is taken at the optimum voltage in the 220V network. If this figure falls to 150V, then the power will drop to 4.8 kW. Basically, with the basic parameters we got acquainted, now let's quickly go through the popular manufacturers.

Stabilizer voltage 220V for the house "calm"

The company "Shtil" produces a wide range of protective equipment. A variety of stabilizers are offered, ranging from low-power households to expensive office models. This domestic manufacturer has several undeniable advantages. First, the affordable cost of equipment. If to compare with the European models, then the saving is about 10%.

The "Calm" model R 110 is used at a voltage range in the network of 165-265V. At the same time this unit can boast stabilization plus / minus 7%. This is hardly suitable for sensitive electronic equipment. The price of such an aggregate is only 2,900 rubles. But R 16000 with a capacity of 16kVA gives a stabilization of +/- 4%, which is already suitable for complex sensitive equipment. But such an aggregate costs 70,000 rubles. It is advisable to install it in offices where there is a high total load on the network. In general, this is an excellent manufacturer. The quality of assembly of equipment is high, and at the same time its cost is quite affordable.

Products of the company "Energia"

You probably noticed that the most attention is paid to the domestic manufacturer. The fact is that this technique is in high demand for several reasons. The first is the affordable cost, and the second is the ease of maintenance and repair. Believe me, with any breakdown it's much easier to find spare parts for the stabilizer "Calm" or "Energy", rather than the European model.

As for this particular manufacturer, many consumers leave positive feedback. For example, the demand stabilizer voltage 220V for the house "Energy" SNVT-500/1. This protective equipment with a capacity of 0.5 kVA. This stabilizer is made especially for connection to gas equipment. Most 2-circuit boilers have a huge amount of accurate and sensitive electronics that do not like even the slightest voltage drops. This unit is able to stabilize the voltage to +/- 3%. All this for 2 900 rubles. The company also offers more powerful models, such as ARS-1000, 1500 and others. Choose the technique depending on the power, and everything will be in order.

What do consumers say?

Here you already know how to choose the right voltage regulator 220V for the house. Which is better, unequivocally difficult to say. For example, for small loads and connecting accurate sensitive electronics, the Energia technique is excellent. If the load on the protective equipment is significant, but the deviation of the stabilization is within 8%, then we can safely give preference to the "Calm" technique. Fortunately today there is a choice, and quite large. If you do not trust the domestic manufacturer, then the European stabilizers in our market are full. Most of them, especially German, Italian, etc., are very qualitative. But there are often problems with timely repairs, as 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 voltage regulator 220V for the house. The wall version of the accommodation, by the way, is very convenient. Many consumers say this. The unit is mounted on the wall with the help of fasteners and does not take up space in the room. In the rest, where such equipment will stand, it does not matter. Of course, we are now talking about houses and apartments, rather than offices and production 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 breakdown due to power surges in the network.
