Description:
The Acuvim 3 is Accuenergy's top-tier power quality analyzer and revenue-grade energy meter. It measures energy to IEC 62053-22 Class 0.1s / ANSI C12.20 Class 0.1 and performs power quality measurement to IEC 61000-4-30 Class A, with IEEE C37.118 synchrophasor (PMU) capability. It samples at 1024 samples/cycle, captures waveforms at 512 samples/cycle into 32 GB of storage, and communicates over dual Ethernet, RS485, USB-C and optional Wi-Fi using IEC 61850, DNP3, Modbus, BACnet, EtherNet/IP, MQTT and SNMP. It is intended for utilities, data centres, battery storage, industrial plants and any site requiring critical power quality and revenue metering.
