Today, houses and apartments are equipped with a huge amount of electronic equipment. In the dwellings there are refrigerators, TVs, video equipment, computers and other devices. However, they can quickly fail during voltage surges in the central network. To prevent this from happening, it is better to purchase a specialized stabilizer. He will positively act on voltage, changing it to the optimal value.
Today there are a large number of such devices in the store. They differ in power, price category, manufacturer, principle of work and other technical characteristics. To choose the right product for a particular device, you need to learn about its parameters. The power of the unit should be higher by 10-30% of the one that the current consumer requires. In this case, a reserve will be created, which will positively affect the functioning of technology.
Products can be either single -phase and three -phase. You need to choose the model, the indicators of which coincide with the requirements of your network. However, you can do otherwise. If your network is three -phase, then you can purchase three single -phase units. So it will be much easier for products to cope with network loads.
Modern voltage stabilizers have different accuracy. For most devices, products are suitable, the parameter of which is in the range of 5-7%. However, for sensitive household appliances, an unit is required, the accuracy of which is no more than 1-3%. If you doubt which device is suitable for your equipment, then consult a specialist working in the store.
Some products are additionally protected from overstrain or short circuit. This helps them work even in difficult conditions. In addition, protection makes it possible for a stabilizer not to break even with a long absence of voltage in the central network.
The unit may also have an output voltage control system. It makes it possible not to break the devices that are connected to the device, even if the latter has ceased to function normally.
There are models that allow the user to independently adjust the output voltage. They can be used for technology that is designed for Western standards. For example, some equipment works only with a voltage of 230 V.
