Dehn provides safety for automation systems
July 2015
System Integration & Control Systems Design
Failure of automation systems, and the resulting drop in production capacities, can result in enormous costs for manufacturing companies. Therefore, high availability is critical for both measuring and control systems and power supply systems. However, these systems are highly vulnerable to lightning and surge effects. With its comprehensive portfolio, DEHN offers numerous solutions for protecting automation systems.
The new DEHNguard DC surge protective device safely protects systems against lightning effects and surges. The powerful switching device DCD of this type 2 surge arrester is designed in such a way that the protective device is safely disconnected in case of overload, thus preventing switching arcs and fire damage. Depending on the voltage level, DEHNguard DC can be used without additional backup fuse in case of direct currents up to 300 A. It is ideally suited for use in safety lighting systems, emergency power supply systems, systems for direct supply of DC drives, control circuits and any kind of battery-operated supply systems.
The equipotential bonding enclosure of type DPG LSA DPG is a lockable metal enclosure for the installation of wiring and protection components. Available in four different sizes, the lightning current carrying enclosure provides terminals that allow it to integrate surge arresters and shields in the bonding system.
SAK 10 AS V4A is a lightning current carrying shield connection system for anchor bars. As, in the course of time, the cable materials are subject to a yield, this yield is compensated by a slipping spring element. The shield connection can also be isolated from local potential by means of an adequate insulating joint. Moreover, this system can be retrofitted without interrupting the conductor shield.
