As you know, power is constantly increasing. Some users with the inclusion of powerful devices in the network often is a "landing", a significant decrease in the brightness of bulbs in the house. This is, primarily, is due to the fact that voltage is not always consistent with the stated 220 volts, and power devices – electric kettles, water heating systems, refrigerators, and is growing steadily. Also, some expensive equipment – computer technique, deep-well pumps, tele-video equipment, special medical equipment can be damaged by power surges or, say, lightning. To protect the expensive equipment and stabilize the output voltage in recent years have increasingly used a special device – the stabilizers. In fact, the voltage regulator is a controlled transformer turns ratio is changed by electronic circuit providing a voltage of 220 volts. Distinguish electromechanical step and ferroresonance stabilizers. Electromechanical regulators – the most reliable, as a rule, different compact, high accuracy output voltage retention.
There are one-and three-phase main field of application – private houses, small businesses and enterprises, polyclinics and medical centers. Electromechanical Regulators can function at low input voltage, which is also not a little important. Step – the most common, popular and affordable. Have a wide input voltage range, high accuracy output voltage and a high degree of protection. Finally, the third type, ferroresonance, they are distinguished by a high degree of protection, only the stabilizers of this type can withstand temperatures as low and high contrast, from -40 to 40 degrees and high humidity, they can be placed in cold areas. Unfortunately, they are not without drawbacks, and – a large, noisy work. Distinguish one-and three-phase stabilizer, and the choice should be paid firm and country producer. Chinese machines, filling the market recently, though cheap, but have a low margin of safety, they are frequent cases of failure, so profit by buying them is questionable.
It is worth pay attention to the company's long-established market for electrical equipment – Varcon, Polygon, Proton, Resanta and so on. Important and correct installation of the voltage regulator. It is best to use services of a professional electrician, but this condition will ensure the safety of the equipment and its proper connection. Thus, the specialist will need to be a necessary power. When you connect regulator must ensure that the section of cable is suitable for the current denomination and denomination machines that are set up regulator, exceed the value of current, otherwise the machine will "knock out" and adequate protection will not be achieved.
