When purchasing an automatic voltage protector, especially in industrial applications, it is a crucial task. The size and model of the surge protector directly affect the safety and reliability of the circuit system. This article will introduce the detailed selection of automatic voltage protectors by the voltage protector factory.
Household appliances
Household appliance’s automatic voltage protector is mainly used to protect household appliances such as televisions, refrigerators, air conditioners, etc. According to the different powers of household appliances, the following types of automatic voltage protectors can be selected:
Low-power appliances (such as televisions, electric fans, etc.): select automatic voltage protectors with current capacity ≥2kA, maximum discharge current ≥10kA, and residual voltage value ≤1.5kV.
Medium-power appliances (such as refrigerators, washing machines, etc.): select automatic voltage protectors with current capacity ≥5kA, maximum discharge current ≥25kA, and residual voltage value ≤1.5kV.
High-power appliances (such as air conditioners, water heaters, etc.): select automatic voltage protectors with current capacity ≥10kA, maximum discharge current ≥50kA, and residual voltage value ≤1.5kV.
Residential applications
In the residential field, the power of equipment is relatively low, but the demand for power quality and equipment protection is also important. The selection scheme of automatic voltage protectors for residential applications is as follows:
Rated voltage: Select a suitable automatic voltage protector according to the voltage level of the residence, usually 220V.
Rated surge current: Consider the load characteristics of residential equipment and the possible surge current level, select an appropriate rated surge current, and generally recommend a protector of 5kA or more.
Environmental conditions: Consider the safety and comfort of the residential environment, and select an automatic voltage protector with a compact appearance and easy installation.
Old urban communities are generally built a long time ago, with incomplete lightning protection facilities, or have been destroyed, and have been in disrepair for a long time, and there are great lightning protection safety hazards. In this case, it is necessary to install an adaptive automatic voltage protector at the power supply to ensure indoor power safety. In addition, with the development of rural modernization and urbanization, rural houses also need to install automatic voltage protectors.
The selection of household automatic voltage protectors needs to be determined according to the power demand of the family and the power of electrical equipment. I use a universal automatic voltage protector, which can effectively prevent electrical equipment from being damaged by voltage fluctuations. The advantages are simple installation, easy use, and moderate price. For households that need to protect multiple high-power electrical appliances, it is recommended to purchase large-capacity or multiple automatic voltage protectors.
Automatic voltage protectors provide a stable voltage supply, thus ensuring the stable operation of electronic equipment. Both home appliances and office equipment can benefit from it.
In practical applications, it is important to choose a suitable automatic voltage protector. Different electronic devices have different requirements for protectors, so they need to be selected according to specific circumstances. At the same time, correct installation and maintenance of the automatic voltage protector is also the key to ensure its effective work.
