What are the voltage regulators ?

Today the low voltage network - is very topical issue and solve it the best one way - to buy a voltage regulator (CH), which will protect all the equipment in the building from failure.To choose the right device, you must first deal with its variants, as well as the principle of operation of each of the embodiment.Next we will look at the pros and cons of the main types of voltage regulators for the home, namely, relay, electronic, electromechanical, ferroresonance and inverter.

  • Relay
  • Electronic
  • Electromechanical
  • Ferroresonant
  • Inverter


relay or as they are called step-stabilizers are the most popular for use in the homeand in the country.This is due to low-cost devices, and high control accuracy.The operating principle of the relay model is switched on the transformer windings by means of a power switch which is triggered automatically.The main disadvantages of this type of heart failure is considered a step change in voltage (not smooth), the distortion of the sinusoid and limited output power.However, judging by the reviews on the Internet, the majority of customers are satisfied with the devices, becauseprice is a fraction of more advanced models.Representative of the relay type stabilizer for the house is Resanta ASN-5,000 N / 1-C, which you can see in the picture below:

Electronic CH can be triac and thyristor.The principle of operation of the first built in the switching between the windings of the autotransformer via triac, so this type of voltage regulator has high efficiency and fast response to alarm.In addition, TRIAC models operate silently, which is another advantage of the variety of CH.With regard to the thyristor, they also proved themselves well and are popular in the home.The only drawback of the electronic type devices - the higher cost.

Electromechanical Electromechanical

CH also called servomotornymi or servo.Work such stabilizers due to movement of the carbon electrode on the auto-transformer windings due to electric drive.Electromechanical devices can also be used to protect the appliances in the house, apartment and dacha.The advantage of this type of stabilizers - the low cost, stepless voltage regulation, and compact size.Of the minuses can be identified increased running noise and low performance.

Principle of HF is built on ferroresonance effect voltage in the circuit capacitor-transformer.This type of protective device is not very popular among consumers because of the noise in, large size (and, respectively, and significant weight), and the lack of opportunities to work in case of overload.Ins ferroresonance stabilizers are considered a long life, precision adjustment and the ability to operate in high humidity / temperature environments.

most expensive type of voltage stabilizers, which are used not only at home but also at work.The operating principle of inverter models is to convert AC to DC (at the entrance) and back to AC (output) due to a microcontroller and crystal oscillator.The undoubted advantage of inverter CH dual conversion is considered a wide input voltage range (from 115 up to 290 volts), and high-speed control, quiet operation, compact size, and the presence of additional functions.Regarding the latter, the HF inverter can further protect appliances against overvoltage, as well as the rest of the interference of the external electric network.The main drawback of the devices is considered to be the highest price.

So we looked at the basic types of voltage regulators.I would also like to note that there are some types of heart failure, as a single-phase and three-phase.In this case, you should choose a model depending on what kind of stress you have in the network - 220 or 380 volts.
