1. Overview

In industrial production, commercial operation, and public building electricity management, precise measurement, intelligent regulation, and compliance are core requirements. With comprehensive functions and outstanding advantages, the Ankerui APM521 multifunctional meter has become the preferred equipment for many scenarios.

2. Functional advantages

From a functional perspective, APM521 can be called an "all-in-one" electricity meter. It supports high-precision measurement of core electrical parameters such as three-phase current, voltage, power, and energy, and performs particularly well in the multi rate function. It can set 4 time zones, 14 daily time periods, and 5 rates (including peak, flat, valley, and deep valley), accurately adapting to time of use electricity pricing policies in different regions and providing data support for users to split electricity consumption in different time periods. At the same time, the electricity meter also has harmonic monitoring and demand statistics functions, which can capture power grid harmonic interference and electricity load fluctuations in real time, helping users detect electricity anomalies in a timely manner.
