Phoenix Contact DC Grids

Phoenix Contact DC Grids offers efficient energy distribution for future industrial systems. These grids enable the direct use of energy from renewable sources, storage systems, and industrial loads, resulting in lower conversion losses and higher overall system efficiency. DC grids optimize energy usage, reduce peak loads, and improve system reliability by allowing energy recovery and intelligent distribution. Phoenix Contact provides a wide portfolio for protection, safe connection, and control in DC grids.

DC Connectors ArcZero

ArcZero DC connectors provide safe make-and-break functionality under load, reducing the risk of arc-fault incidents. This capability allows specific system sections to be disconnected as needed, enhancing system availability and simplifying maintenance. The connectors' robust mechanical design also ensures long-term reliability in harsh industrial and energy applications.

• Protects operators and components reliably against arc faults and can be safely plugged and unplugged under load
• Tool-free locking for safe and easy handling
• Enables time-saving maintenance and the replacement of connected devices, reducing downtime
• Long service life due to high mating cycles

EMpro DC Energy Meter

EMpro DC energy meters are designed with tamper protection and certified approvals. These meters support accurate watt-hour (Wh) billing while helping prevent unauthorized access. Features include a compact footprint, efficient heat dissipation, and reliable performance across a wide temperature range.

• Space-saving design
• Precise DC direct measurement up to 650kW
• Tamper-proof electromechanics and firmware
• High reliability with an extended temperature range
• Seamless integration through a simplified point-to-point protocol

Power Electronics for DC Grids

Phoenix Contact delivers reliable power electronics for DC networks. Active AC/DC power supply units, known as Active Infeed Converters (AICs), enable efficient DC grid integration with public AC grids. Thanks to bidirectional operation and certification to VDE-AR-N 4110 and VDE-AR-N 4105, excess energy can be safely returned to the utility network. The TRIO POWER AC/DC power module supports grid conversion, while CHARX 19-inch power modules provide straightforward integration of DC sectors with flexible DC input and output ranges.

• Efficient operation due to high efficiency and high power density
• Scalable power through flexible interconnection of the modules
• Safe operation due to numerous integrated protective functions
