Accuenergy Acuvim-L power meter

Revenue-grade multifunction power and energy meter, at the core of compressed-air energy audits. Panel-mount (LCD) or DIN-rail transducer, accepts 5 A, 1 A, 333 mV and Rogowski-coil (AcuCT Flex) current sensors, and speaks Modbus-RTU / BACnet MS-TP out of the box — with Modbus-TCP, BACnet-IP, Wi-Fi and 8 GB data logging via the AXM-WEB2 modules. Assemble the exact part number with the configurator.
