SUG-7-DIN / M-BUS, surge protector for RS-485 bus, dedicated to industrial automation and CCTV.

SUG-7-DIN / M-BUS is a high-quality surge protector, protecting the communication bus from damage caused by atmospheric discharges and various types of surges. It eliminates and grounds large electrical charges (up to 10kA) and also eliminates potentials between individual conductors of the transmission lines (within the wires).

The surge protector is mounted on a standard DIN rail of 35mm. Sliding locks placed on both sides facilitate the installation of SUG-7 in any position. High-quality window clamps with a high current load limit reduce the risk of damage during large impulse shocks. The device occupies the width of one module of the DIN standard.

The surge protector utilizes an innovative solution in the form of a super-fast MOSFET fuse, which additionally protects the drivers from current impulses of potential differences between individual devices and overloads resulting from short circuits or overloads.

In the event of a current surge above 300mA, the circuit between the input and output of SUG-7 is disconnected in 1μs. After the threat subsides, the connection is restored within 1μs.

Due to the possibility of surges occurring from any side, it is recommended to connect surge protectors at both ends of the bus, which increases the reaction speed and the level of protection. SUG-7-DIN should be grounded using an individually made grounding point or using the PE line - however, attention should be paid to ensure that the path of discharged charge to the ground is as short as possible.
