Relay stabilizers are devices that are designed to normalize the operation of the electrical network in the house. Such devices are very popular due to the fact that they have a very simple design and principle of operation, which in turn affects the low cost of production.
Main features of devices
Before you buy a relay stabilizer , it is imperative to understand all the features of such a step device. Its principle of operation is as follows:
- Initially, the device measures the voltage level of electricity that is supplied to it from the electrical network of the house.
- Next, the current level is compared with the normal values required at the output.
- At the end, the device determines the difference in volts to be added or subtracted.
- Knowing the difference, the device selects one or another relay to which it is necessary to send current.
As a result, the relay regulator raises or lowers the voltage level to normal values, corresponding to the needs of the household appliances used at home.
Benefits
The need for relay stabilizers is directly related to the advantages of such devices. They are as follows:
- Small overall dimensions. This is due to the fact that a complex large winding system is not needed to compensate for the difference in the number of volts at the output and at the input.
- Wide input voltage range. The models available on the market work with quantities ranging from 100 to 280 units.
- Wide range of operating temperatures. Most of the models of devices are designed so that they can operate smoothly within the ambient temperature range from -40 to +40 degrees Celsius.
- Low noise level. The device emits not very loud sounds only in the process of switching the relay.
- Low sensitivity to distortion or current frequencies that are analyzed at the input to the device.
- Allowable significant overload for a long time, reaching 110%. This is due to the fact that the relay operates with low voltage currents.
The service life of relay stabilizers is also a very important factor that you should pay attention to when purchasing. Such devices can be used for 10 years without the need for repair or maintenance.
