При возникновении перенапряжения устройство защиты от перенапряжения немедленно отключает питание. Этот вид сетевой фильтр is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of сетевой фильтр is generally made of current sensor. The composition of the control board and the lock. The purpose of the current sensor is to detect whether the grid voltage has fluctuations in the сетевой фильтр. When the control board loads the surge voltage data signal of the current sensor, the lock is operated immediately, as the conduction of the actuator control circuit. There is another сетевой фильтр electrical circuit, which does not disconnect the power circuit when the сетевой фильтр is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the сетевой фильтр. This type of circuit is usually placed inside a circuit board, such as a switching power supply circuit. Surge protector class 1. Cross-border marketing is between the live wire and the neutral wire, that is, the differential mode suppression power circuit. The second and third level jumpers of the сетевой фильтр are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode сетевой фильтрs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode сетевой фильтрs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for сетевой фильтрs with lower requirements, the assembly of сетевой фильтрs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
