    Voltage Stabilizer Buying Tips

    1. It is recommended that you choose a voltage stabilizer that is three times larger than the actual power, because in practice, voltage stabilizers have to overcome surge impact of commercial power and start impact of inductive load (such as refrigerator, air conditioner, motor and electric motor). When choosing a contact automatic voltage regulator in the purchase of voltage stabilizer, the rated output voltage regulator should have a larger margin than the switched automatic voltage regulator. In addition, it is necessary to check the appearance, quality and technique, ensuring that buttons, switches and other operations are flexible and reliable, spare parts are tight and there is no sound of object rolling in the machine when shaking the device components, otherwise there are foreign bodies in the device.

    2. The rated total output of automatic voltage regulator should be properly selected (total capacity=total power of household appliances*3). The outline structures of automatic voltage regulators include desktop voltage regulator, wall-mounted voltage regulator, dual-purpose of desktop and wall-mounted voltage regulators, as well as floor-type voltage regulator. It is recommended that you should choose different styles according to the location of installation, main use and installation capacity.
