    Voltage Stabilizer Buying Tips

    1. Before purchasing a voltage stabilizer, you'd better determine the reverse range and frequency of household voltage. For instance, if your voltage is pulled to about 80V and the input range of your voltage stabilizer is between 140 V and 230V, it will not work as you wish. Therefore, voltage stabilizers should be selected according to the power supply range of the service environment. It is recommended to choose a broadband voltage stabilizer.
    2. You'd better know the total power of the device you need to stabilize the voltage, and the rated power of your voltage stabilizer should be 30% higher than the total power of all devices when choosing a voltage stabilizer. You should know that the heat generated by full load will increase the loss of components. When the voltage stabilizer operates overload, the required current will be too large, and the voltage will inevitably be pulled down.
