The fourth industrial revolution is particularly moving the mechanical engineering industry. The constant goal is to increase machine availability and output by means of digitalization.
The EU has agreed on emission reduction targets according to which newly registered heavy utility vehicles should emit on average 15 % less CO2 in 2025 than in 2019. A reasonable possibility to save fuel is the partial electrification with a 48-volt on-board electrical system, which is already taking place in modern passenger cars.
With the implementation of the exhaust emission standard Tier 4 final or EURO 6 for diesel engines in off-highway vehicles, the SCR® technology has made its debut.
Storage and evaluation of all data logged in machinery and plants is the precondition for solutions on the score of “condition monitoring” and also “predictive maintenance”. Plant transparency is significantly enhanced through the consistency within the systems - always aiming at increasing the system availability.
Protecting devices and cables in hierarchical load networks requires precise coordination of the protective elements in use. This ensures that safety ranges do not overlap or have gaps, but provide selective protection. Overload protection at nominal operation and short circuit protection must be observed.
Reliable electrical medical equipment and machines is the basic requirement for successful work in the operating rooms, on the wards or also in the laboratories. Safety and quality must not be compromised. This is particularly true for the protection of devices and machines in the event of overcurrents.
Electrical systems in the chemical and pharmaceutical industry often have long load lines, a DC 24 V supply and many loads supplied by one source. In addition, there are often problems with selective trip in the event of a short circuit at the load.
