Product Features of ZGSD40 / 4P Surge Protector:
For various collection devices of the system, ZGSD40 / 4P will directly affect the operation of the device because the device is directly placed in a dusty environment. It is necessary to focus on moisture, dust and corrosion protection. If the camera is suspended from the shed for a long time, the protective cover and dust-proof glass will soon be covered with a layer of dust, carbon ash, etc., which is dirty and black, and also corrosive, which seriously affects the viewing effect and also brings equipment. Damage, so you must do a good job of dust and corrosion protection of the camera. In some places with heavy moisture, the installation position and equipment protection must be adjusted during the maintenance process to improve the equipment's moisture resistance. At the same time, dehumidification measures must be taken frequently in high-humidity areas to solve the problem of moisture resistance. All components of the protection circuit will be connected in series with the input. 。 Once the inrush current is absorbed by the thermistor, either the triac begins to ignite or the relay turns off . When connected in parallel, that is, when the arrester is connected between the active wire and ground, there is no need to pay attention to the rated current of the arrester, because the rated current does not pass through the arrester. In the case of a circuit equipped with a series surge protector, attention must be paid to its rated current. In a circuit with a high data transmission rate, the attenuation of the surge protector plays a decisive role.
ZGSD40 / 4P surge protector application industry:
ZGSD40 / 4P, ZGSD80 / 4P, ZGSD100 / 4P series surges are 8 / 20μS surges, and they are secondary system surge protectors.
