Voltage stabilizer 380V - an excellent defender

Modern apartments and houses are oversaturatedelectrical appliances. Their excess causes a lack and voltage surges. In order for all household appliances to survive after another drop, consumers have to purchase voltage regulators. The market offers a variety of products at different prices and customer needs.

Appearance

Usually the voltage regulator of 380V has the formA metal box on which there are terminals for connecting input and output wires. Also on the front panel can be placed devices for monitoring the voltage and current consumed by the load in the network. On the body, there are usually a lot of holes and slots for cooling the inner filling, since it can generate a lot of heat under the load.

Inside there is an autotransformer and an electronicblock, in a pair they react to the change in the input voltage and instantly change it, which at the output gives a stable, high-quality current for powering different equipment.

What is it needed for

Many, probably, remember the Soviet times, wheneach tube TV was connected through a humming heavy box. This was a small power stabilizer for 200-250 watts, mainly intended for television receivers. It was noteworthy that they could not be used in cities, but in villages the voltage stabilizer 380V was irreplaceable, since the network had 180 V, and the TV simply did not work. Why did this happen? The fact is that in the villages there were 1-2 substations, and the length of the lines is very long, due to which there was a voltage drop, and besides the house was closer to the transformer, the tension in it was higher, and in the last buildings it was critically small. Then the required voltage regulator of 380V 15 kW was saved.

Voltage stabilizers now

Since those times immemorial, nothing has changed. Transformers and lines basically remained the same, and the equipment and equipment became much more. Repeatedly it was possible to see or read in the news about the appearance of 400V houses in the outlets, which resulted in massive spoilage of electrical property and non-return of damage to the affected residents by the services. This was obtained from overloading of electrical networks and burning of working zero. And although many devices have built-in stabilizers, they may not provide really high-quality equipment protection.

Here, an industrial voltage stabilizer 380V specially designed for this function comes to the rescue. For a house or a modern apartment it is necessary.

Which to choose

In a modern store you can choose a stabilizervoltage 380V and 220V. It is easy to guess that for a regular apartment or house you need a single-phase 220V. Sometimes there are houses where there are three phases, in this case a voltage regulator of 380V is needed. The same applies to small businesses, firms and workshops where machines with engines for three phases are installed.

To not spoil the expensive equipment, the voltage regulator will also help.

With the voltage figured out, now to what currentto buy a device? You might think that the more, the better, but you need to take into account the cost of the device: with the increase in capacity, the price also increases significantly. Therefore, if you overpay, you can not use half of the stabilizer's potential, but you will spend a fair amount of money. Usually 5-10 kW is enough for a house and an apartment. This can be determined by counting all the possible devices in the house and learning the total power.

For a small company, a stabilizervoltage 380 V. If the consumption is much higher, select accordingly. Fortunately, they can be up to 80 kW and above. For each there is one, for different needs.

Particular attention should be paid to qualitypurchased stabilizer. After all, there are a huge number of manufacturers, and it is not always easy to choose among them. I would not like to spend money and get a poor-quality product, which at the first voltage jump will not protect the equipment, and even fail. I wanted to draw your attention to the devices of the company "Resanta". These stabilizers have a fairly low price, but they provide a good quality of stabilization.

Take, for example, a three-phase stabilizervoltage 380V "Resant", providing the maximum permissible load current 6 kW and voltage 380 V ± 2%. Mechanical switches provide the ability to monitor the voltage at the input and output of the device, as well as the current consumption of the load. There is protection against overload and short circuit on the output. Also, natural cooling (without a fan) provides a low noise level, which is sometimes important when installing indoors. The metal case provides rigidity of a design and protection against mechanical damages. In addition, the stabilizer itself has a rather modern and aesthetic appearance, and a weight of 29 kg makes it possible to carry the device without much difficulty. The effectiveness of the stabilizer is also indicated by the declared efficiency - 97%.

Conclusion

Of course, you can do without stabilizer, butIs it worth the risk? By calculating the cost of a TV, a refrigerator, a computer and other, such as business equipment, you will realize that, in which case, the costs will be much greater. And even if the big jumps do not happen, all the same, the voltage stabilizer 380V will ensure a longer life of your electrical equipment.
