Product description: Zamel Supla MEW-01 - 3F+N WiFi electricity consumption monitor
The MEW-01 is an advanced electricity monitor operating within the Supla system, designed for home and industrial applications. It supports three-phase measurement with a neutral conductor (3P+N), enabling simultaneous current, voltage, and power measurement. The module offers Wi-Fi connectivity and Supla Cloud compatibility, allowing remote monitoring of parameters from any location. Thanks to the use of an external SMA antenna , the meter ensures a stable connection even in metal switchboards. The MEW-01 also enables single-phase measurement , making it suitable for use in single-phase installations.
Zamel Supla MEW-01 - 3F+N WiFi electricity consumption monitor.
The module enables remote measurement of electricity in three-phase systems.
Main features of the Zamel Supla MEW-01 meter
- 3-phase + N measurement: energy control on each phase
- Single-phase installation support: versatile use
- External WiFi antenna (SMA): reliable connection in difficult conditions
- 100 A current transformers: set of 3 pieces with 100 cm cable
- Supla Cloud + REST API: full integration with smart home systems
- Bidirectional measurement: data on energy consumed and released
- Data export: to Excel, CSV files and integration with external applications
- Displaying charts: visualization in the Supla app
- Compact design: takes up 2 DIN modules in the distribution board
Installation and connection of the MEW-01 energy consumption monitor
The MEW-01 is mounted in a standard switchboard on a DIN rail (TH35). The module requires a power connection and three current transformers (included), which must be installed in the correct direction of current flow . When the meter is located in a metal switchboard, the SMA antenna can be easily routed outside through a conduit hole. After configuration in the Supla app, the monitor immediately begins collecting data.
Practical applications
MEW-01 is an excellent solution for home users, businesses, workshops, and PV installations requiring reliable, remote monitoring of energy consumption. It works well in both new installations and the modernization of existing systems – without the need to interfere with communication cabling.
The module can be installed directly on a TH35 DIN rail.
