Used for surge protection of electrical circuits, power supply equipment and power ports of other electronic devices; suppress transient overvoltage, discharge impulse current, and establish an equipotential system. (Level 1 power supply lightning protection device. Level 2 power supply lightning protection device. Level 3 power supply lightning protection device.)
Signal lightning protection device is based on the characteristics of signal system, has the advantages of small insertion loss, fast response speed, accurate clamping, low output residual voltage, etc., and superior transmission performance. (Network two-in-one lightning protection device. Control signal lightning protection device. Video signal lightning protection device. Audio signal lightning protection device. Antenna feed signal lightning protection device).
Designed in accordance with the lightning protection requirements of modern household multimedia junction boxes, it can protect indoor communication devices and multimedia equipment from damage induced by lightning.
Special external disconnector (SSD/SCB) for surge protector, with good stability and high reliability. (Backup protector)
Product warranty matters
The N line and PE line of the system are combined into a PEN line from the low-voltage side of the transformer. At this location, only a (3P) surge protector needs to be installed between the phase line and the PEN line. After entering the main distribution box of the building, The PEN line is divided into N line ^ PE line and independent wiring. The PEN line is connected to the general equipotential grounding busbar in the building to connect to the earth.
The N line and PE line of the system are only connected at the outlet end of the low-voltage side of the transformer and connected to the ground. Before entering the general distribution box of the building, the N line and the PE line are independently wired, and the phase line and the PE line must be connected Install a surge protector.
The N line of this system is only grounded at the neutral point of the transformer, and the N line and the PE line are strictly separated. Therefore, it is necessary to install a surge protector between the phase line and the N line, and a switch-type surge protector is often installed between the N line and the PE line.
