Acuvim L Overview

What is a Multifunction Energy Meter?

While some meters may provide only amperes or voltage, a multifunction energy meter delivers additional value by providing real-time, true-RMS measurements of current, power, voltage, energy and many other parameters. Multifunction meters may also provide important power quality information including voltage and current unbalance, THD, and individual harmonics. By providing comprehensive energy information, multifunction energy meters are the ideal choice for monitoring in power distribution systems or in industrial plants.

Customize Your Acuvim L Power Meter

The Acuvim L is a capable multifunction power meter designed for collecting real-time energy data in nearly any environment. With a tough, IP56 rating, the durable Acuvim L can withstand demanding, industrial settings and provide accurate consumption data for distribution feeders, motors, capacitor banks, generators, or other equipment. Configure the Acuvim L to match your project objectives.
