What you need to know about stabilizers when choosing them
To determine the choice of a stabilizer for your home, it is worth familiarizing yourself with its main characteristics:
- Type of transformer. Relays are cheaper, but they are noisier and do not guarantee maximum accuracy. Electronic devices do not have these disadvantages, but they are much more expensive. Combined devices are most common - they are the golden mean in terms of price to quality ratio. Electromechanical — have a wide range and high accuracy, but at the same time the speed of response and reliability is somewhat reduced.
- Number of phases. The manufacturer offers two options: single-phase and three-phase. For a three-phase network in the house, you can build a scheme with three single-phase stabilizers, one for each phase.
- Voltage range. Indicates the minimum and maximum voltage values that the device is able to normalize.
- Type of housing. There is a floor and wall mounting type. The second is more convenient, but it is more difficult to install. If the walls of the house are thin, it is better to buy the floor variety.
