Product description: Zamel Supla MEW-02 ETH - 3F+N WiFi/Ethernet electricity consumption monitor
The Zamel Supla MEW-02 ETH module is a professional electricity monitor designed for both home and industrial applications. Thanks to two communication modes - WiFi 2.4 GHz and Ethernet - it enables stable and flexible access to measurement data. You can track energy consumption and production, current intensity, voltage and power on each of the three phases in real time . The advanced Supla application allows for convenient data management, receiving notifications about anomalies and creating extensive historical reports. MEW-02 ETH is compatible with many current transformers (SC-16 (100 A), SC-24 (200A), SC-36 (400A) and SC-2000), which allows for adaptation to various electrical installations. The device supports the MQTT and API protocols, which facilitates integration with automation and energy management systems.

Energy meter connection diagram
The MEW-02 ETH should be connected to the electrical installation in accordance with the diagram in the user manual.
- Voltage supply terminals: connect the phase wires to terminals V1, V2, V3 and the neutral wire to terminal N.
- Current transformers: connect the red wire to the S1 current input and the black wire to the S2 current input of the corresponding channel (I1, I2, I3). Additionally, the direction of current flow must match the arrow on the transformer.
- Power: After properly connecting the power cables and transformers, power up the unit and check that the LEDs indicate correct operation of each phase.
Make sure that all connections are made according to the manufacturer's instructions to avoid measurement errors and ensure installation safety.
There is a module connection diagram on the housing.
With the Supla application you can monitor installation parameters in real time.
