Electricity energy meter monitor WI-FI 3F+N, FOX ENERGY 3 WI-MEF3 400A WI-MEF-3-400

Intelligent energy consumption monitoring in your installation

Are you looking for a way to precisely control your building's electricity consumption? The FOX ENERGY 3 WI-MEF3 electricity energy monitor is an advanced device that allows you to track network parameters and optimize costs. Designed for three-phase installations with a neutral wire, it offers detailed data on energy consumption, voltage and current, and thanks to Wi-Fi communication, you have access to it from anywhere. This is an ideal solution for both homeowners with photovoltaic installations and professional installers looking for a reliable tool for energy analysis.

Functionality and application

The device measures active and reactive energy, providing comprehensive information about the operation of the electrical installation. This allows you to monitor power consumption by individual phases, identify potential problems and take action to reduce energy losses. Monitoring is done via a mobile application or web browser, providing convenient access to real-time data and measurement history. Mounting on a DIN rail (DIN rail adapter) is quick and easy, and the compact dimensions (35 mm wide and 2 modules) allow for discreet integration with existing infrastructure.

Key features and benefits

• Wi-Fi communication: remote access to measurement data from anywhere.
• Three-phase measurement with neutral wire: ideal for most home and industrial installations.
• High measurement accuracy (class A): reliable data for precise energy analysis.
• Network parameter monitoring: voltage, current, active and reactive power – a complete picture of the installation's operation.
• Easy DIN rail mounting: quick integration with your existing distribution board.
• Current transformers included: no need to interfere with live wires during installation – safe and non-invasive installation.
• Counter rollback protection: protection against data manipulation.
• Measurement range up to 400A: can be used in installations with high loads.
• Wide range of rated voltages (230/400V): compatibility with different power systems.

The device is designed for indirect/semi-indirect measurement, which means it uses current transformers to measure the current value in the circuit. This allows you to monitor large loads without having to directly connect the device to high-voltage wires. The device's own power consumption is minimal (2W), which does not significantly affect the overall energy consumption of the building. The IP20 protection class provides protection against accidental contact, but does not protect against moisture or dust – the device should be mounted in a dry and well-ventilated place.
