Description:
The Acuvim II is a multifunction power and energy meter for power monitoring, kWh metering and power quality analysis in commercial, industrial and utility installations. It offers revenue-grade accuracy (IEC 62053-22 Class 0.1s / ANSI C12.20 Class 0.1), four-quadrant metering, harmonics to the 63rd, data logging and Time-of-Use. The IIR model provides data logging and TOU; the IIW model adds IEC 61000-4-30 Class S power quality event logging and waveform capture. Plug-in AXM modules add I/O and Ethernet, Wi-Fi, fibre and industrial protocols such as IEC 61850, BACnet, DNP3, EtherNet/IP and MQTT.
