3-Phase+N Electricity Energy Meter Type: MEM-21 EXL10000026

Intelligent energy consumption monitoring in three-phase installations

MEM-21 is an advanced energy meter designed for precise measurement of network parameters in three-phase systems with a neutral wire. The device allows for a detailed analysis of energy consumption, both drawn from the grid and fed back – making it an ideal solution for installations with renewable energy sources, such as photovoltaic panels. Thanks to cooperation with the EFC-01 controller and the possibility of data archiving in the cloud, MEM-21 provides full control over energy consumption and cost optimization.

Precise measurements and versatile application

This monitor measures voltage, current, active, reactive and apparent power for each of the three phases. The measurement is performed using SC-16 current transformers (included), which guarantees accuracy even under high loads. MEM-21 can operate as a consumption monitor, a sub-meter in PV installations, or measure both energy consumption and production. This makes it indispensable in homes, businesses and industrial facilities. The device is adapted for mounting on a TH35 rail in a standard electrical distribution board.

Functionality and ease of use

MEM-21 offers a range of features to facilitate data analysis and energy management. The ability to remotely update the software ensures access to the latest functionalities and fixes. The device indicates the presence of voltage on individual phases, and the collected data can be exported to a .xlsx file for detailed analysis. Additionally, the detachable antenna allows connection of an external antenna for better radio transmission range (868 MHz). Please note that having the EFC-01 controller with an active Exta Life Cloud service (free service) is necessary for the full functionality of the device.
