Industrial DC grid in the automotive industry
In the automotive industry, direct current is considered the key technology of the future and large German companies are pioneers in its integration. Protecting, monitoring, and switching DC sectors to an existing DC infrastructure are technical challenges – and Phoenix Contact already has an answer.
The CONTACTRON ELR HDC DC circuit breaker was developed for exactly these tasks. It monitors operating current and voltage and, with its pre-charging function, prevents current peaks when switched on. In the event of an overcurrent, there is a three-stage shutdown.
Application in building automation - DC grids
Integrating direct current into building automation also requires innovative switching and protective devices. Handling DC loads, especially pre-charging and switching, and monitoring voltage and current are crucial. Extremely short shutdown times improve operational safety in the event of errors. Energy efficiency in the overall system is increased by reducing the number of energy conversions (e.g., AC/DC). Direct DC feed-in (e.g., when using photovoltaic systems) also reduces energy losses.
DC power grids in industry are becoming increasingly important on the road to more sustainable production. Phoenix Contact is committed to the safe use of DC technology and is researching comprehensive DC-based smart grids together with other companies. Learn why direct current is the industrial energy system of the future and what it has to do with sustainability.
