Innovative inner workings ensure the safety of DC connectors.
Phoenix Contact offers the ArcZero series DC connector to address safety risks associated with DC power grids. Despite its efficiency improvements and simplified installation, direct current is prevalent in electronic devices and production machines. Despite the decline of DC technology, direct current is making a return in the form of intelligent DC grids in an electricity-led energy revolution.
Into the future with direct current
Countries worldwide are actively working to reduce net carbon emissions to zero by enhancing both renewable energy availability and energy efficiency. To achieve this, there is a concerted effort to modernize power stations, upgrade motors, optimize industrial processes, and renovate buildings. In parallel, the adoption of direct current loads is rising in diverse devices such as lighting, IT infrastructure, and electric motors. Notably, the transition to energy-efficient LED lighting is replacing traditional incandescent lamps, while inverters in intermediate circuits contribute to heightened efficiency. Direct current, pivotal in power generation and consumption, assumes a central role across various societal areas.
Requirements on DC connectors
Direct current displaces alternating current, changing component requirements and grid behavior. Protection concepts cannot be adopted one-to-one, and grid behavior varies significantly. The electric arc during switching and disconnecting operations is crucial in DC applications, as zero crossings occur 100 times per second. Phoenix Contact has conducted test programs to understand DC electric arcs, developing technologies and prototypes for safely connecting and disconnecting connectors in DC power grids. ArcZero is a new connector for DC power grids.
ArcZero tames the arc
The ArcZero connector features integrated electronics that actively quench the electric arc, providing the same level of safety as AC connectors. This reduces wear and increases connector longevity. It allows safe connection and disconnecting under load, ensuring high availability. The connector is designed for IP69 protection, high-impact strengths, and long-term outdoor suitability. It can connect end and distribution circuits up to 20 amps and 400 volts or 800 volts. It is user-friendly and cost-effective, with numerous insertion cycles.
