This series of products can be used in the protection of the industrial control network, RS422/485 interface, dedicated circuits, automatic control and instrumentation lines, data lines, telephones, facsimile apparatus, and other equipment, as well as the sensors and secondary meters in the circuit loop; Meanwhile, they can suppress induced lightning strokes from signal lines to prevent system equipment being damaged.
Before connecting the SPD into the system, first check the ground resistancer of earth mat which should meet relevant requirements of specifications. The SPD should be connected in the front end of protected equipment, with the output end reliably connected to protected equipment. The earth wire should be as short as possible to be connected with the protective ground strap of the equipment room. The product can be conveniently installed in any explosion-proof places.
The signal SPD is sealed in the metal shell. Characterized by the fast response speed (ns), low protection level, small volume, and light weight, the SPD can be installed conveniently with the connection mode of terminal blocks.
