This “Heavy Load” subrack was especially designed for rough environments, to ensure efficient electronics for railway technology, energy and power stations, for strongly vibrating machineries or defence industry.
Due to the strengthened and extended front brackets as well as the double fixed module rails, the heavy load subrack is ideal when you need a subrack that can easily endure shock and vibration. Furthermore, higher weight capacities can be taken. This has been confirmed by an independent institute that did tests for resonance, vibration and shock. Its EMC compatible design has been approved by a test as well and the interference resistance is high.
