The ACR10R is a rail-mounted multifunction electrical instrument designed for energy-saving upgrades and real-time power monitoring in high-energy industries, PV installations, and distributed power systems. It allows non-intrusive current measurement using external Rogowski coils or split-core current transformers, eliminating the need for disconnecting live conductors. With built-in Modbus-RTU communication, LCD display, and support for both remote signaling and control via relay output, the ACR10R offers a versatile and safe solution for energy data collection and smart control systems.
