What you need to know about stabilizers when choosing them
To decide on the choice of a stabilizer for your home, you should familiarize yourself with its main characteristics:
- Transformer type. Relay ones are cheaper, but at the same time they work more noisily and do not guarantee maximum accuracy. Electronic devices do not have these shortcomings, but they are much more expensive. Combined appliances are most common - they are the golden mean in terms of price and quality. Electromechanical — have a wide range and high accuracy, but at the same time, the response speed and reliability are somewhat reduced.
- Number of phases. The manufacturer offers two options: single and three-phase. For a three-phase network in a house, you can assemble a circuit with three single-phase stabilizers, one for each phase.
- Voltage range. Shows the minimum and maximum voltage indicators that the device is able to normalize.
- Hull type. There is a floor and wall mounting type. The second one is more convenient, but it is more difficult to install it. If the walls of the house are thin, it is better to purchase a floor variety.
