The Sync Energy EVA400CT1 is a 400A CT clamp designed for higher-capacity Sync Energy EV charging and load management installations. It is used to monitor larger incoming supplies and provide real-time current measurement for compatible Sync Energy wall chargers and EV Balancer systems. By measuring the electrical load on the supply, the EVA400CT1 helps the system dynamically manage charger output and prevent the installation from exceeding the configured supply limit. This makes it suitable for larger residential, commercial and multi-charger applications where higher current monitoring is required. The EVA400CT1 provides a practical solution for installations requiring precise load monitoring and robust supply protection. It supports dynamic load management, helping optimise available power while maintaining safe and reliable EV charging operation.
