Description:
The Acuvim L is a cost-effective multifunction power and energy meter for panel and device monitoring in commercial and industrial installations. It provides revenue-grade accuracy (Acuvim EL: IEC 62053-22 Class 0.2s / ANSI C12.20 Class 0.2; Acuvim CL: Class 0.5s / Class 0.5), four-quadrant metering, harmonics, alarms, Time-of-Use and 8 MB of onboard logging. An RS485 port with Modbus-RTU and BACnet MS/TP is standard, and the same AXM I/O and communication modules used by the Acuvim II add Ethernet, Wi-Fi, fibre and protocols such as Modbus-TCP, BACnet-IP, IEC 61850, PROFINET and MQTT.
