Regenerative AC Power Supply

High power 4-quadrant AC source-load with comprehensive emulation capability

NEXUS regenerative AC power supply is the alternating current variant of NEXUS DC Power Supply and further equipped with comprehensive emulation capabilities and programming functions. NEXUS AC Power Supply applies for grid compliance and compatibility validation through bidirectional architecture and versatile grid emulation functions, addressing critical testing needs in the renewable energy sector including anti-islanding protection and off-grid load simulation.

As programmable source-load unit with auto-ranging functions with high performance and technical specifications, NEXUS features advanced regenerative load technology that recovers up to 100% the current back to the grid with a regenerative efficiency of 91% and thus minimizing energy consumption, reducing operational costs.
