1. Please determine the range and frequency of the 220V voltage jump in your household before purchasing a voltage regulator. For example, if your home voltage is being pulled to around 80V, but the input range of your voltage regulator is between 140V-230V, it will definitely not achieve the effect you want. Therefore, voltage regulators should be selected based on the power supply range of the usage environment. Advocate for selecting broadband voltage regulators.
2. Rated power. Please determine the total power of the equipment you need to stabilize. When selecting a voltage regulator, it is best to have your rated power higher than 30% of the total power of all devices. You should know that the heat generated at full load will increase the energy consumption of the equipment. If the operation is overloaded, the required current will be too large, and the voltage will inevitably be pulled down.
3. Active voltage regulation function and accuracy. When purchasing a voltage regulator, try to choose one with active voltage regulation function, although the price may be slightly higher. But it's much more cost-effective than the economic losses caused by burning your machine. The old-fashioned voltage regulator utilizes the principle of relay switching when voltage changes. At the moment of switching, there will be a slight surge in current. Therefore, the higher the accuracy, the smaller the current impulse
4.When purchasing a voltage regulator, it is recommended that you choose a voltage regulator that is three times larger than the actual power, Due to the fact that voltage regulators have to overcome the surge impact of mains power and the starting impact of inductive loads in practical work When purchasing a voltage regulator, such as a refrigerator, air conditioner, motor, and electric motor, when selecting a touch type active voltage regulator, the rated output voltage regulator should have a greater margin than the adapter type active voltage regulator. Check the appearance quality and processing technology, and the buttons, switches, and other operations should be flexible and reliable. The components should not be loose or shake the machine. There should be no rolling or moving objects inside the machine, otherwise it indicates that there are foreign objects inside the machine.
5. Reasonably select the rating of the active voltage regulator Fixed output total, total capacity=total power of household appliances × 3. There are several types of external structures for active voltage regulators, including desktop, wall mounted, dual-purpose, and floor mounted. Different styles should be selected based on the installation position, main purpose, and installation capacity.
