Electromechanical single -phase stabilizable devices are autotransformers, where the output voltage is smoothly adjustable due to the fact that the graphite brush moves along the coil of the transformer. The speed of processing distortions in the electric network limits the tendency of graphite brushes to wear, but it is able to stabilize the work of not only household, but also medical and industrial devices.
Advantages: for an electromechanical single -phase stabilizer is characterized by high accuracy of the output voltage and high reloading ability.
Technical characteristics: the value of the input voltage depends on the manufacturer and can vary in the range of 140-260 V or 160-250 V. Output voltage regulation accuracy – 2 or 3 percent. Power is from 0.5 to 30 kW. The weight of the apparatus is from 5 to 80 kilograms.
Price range: from 40 to 1100 US dollars.
Single -phase stabilizers with stepped regulation
These devices are two types: relay and electronic. During their operation, the transformer turns are switched using keys, in other words, an automatic switch is used. In a digital or electronic single -phase stabilizer, the switch is made in the form of symistors and thyristors, in the relay automatic switch mechanical. Stabilizers with stepped regulation are characterized by a high speed of distortion processing in the mains, but at the same time they are characterized by a high error in output voltage. Suitable for home and office use.
Advantages: such devices are not threatened with mechanical wear of parts, only a transformer rustles during operation, the operation of electronic keys is silent, low sensitivity to the frequency of an electric network.
Technical characteristics: input voltage value is 140-260 V. Power varies from 0.5 to 10 kW. Output voltage regulation accuracy – 8 percent. The weight of the apparatus – from 3 to 18 kilograms.
The price range: the cost of relay stabilizers starts from $ 30, digital costs from 40 to 250 US dollars.
The reputation of a reliable and inexpensive device was won by the Lider Best stabilizer, which is a budget modification of the series W. The input voltage parameters of this apparatus fluctuate in the range of 135-270 V, which is somewhat already than that of the series W. The output voltage is adjustable with an accuracy of 5 percent. The work of the stabilizer is controlled using LEDs.
