Set: energy consumption monitor MEF-3-OPTI-40 FOX with indicator light LK-BZ-3 WI-MEF-3-OPTI-40SET

Intelligent energy consumption monitoring with the F&F FOX kit

This kit is a comprehensive solution for monitoring electricity consumption in domestic and industrial installations. It consists of a three-phase energy consumption meter-counter MEF-3-OPTI-40 and a signaling lamp LK-BZ-3, providing not only measurement but also additional circuit protection. The kit is ideal for both standard installations and systems with renewable energy sources, such as photovoltaics or heat pumps.

Versatile application and precise measurements

The Wi-MEF-3-OPTI-40 monitor allows for current measurement of power consumption, voltage and currents, as well as recording average, minimum and maximum values. This allows users to accurately track energy consumption, identify potential problems and optimize installation performance. The bidirectional, four-quadrant measurement makes the device perfect for monitoring both energy consumption and delivery to the grid – crucial in the case of photovoltaic installations.

Comfortable operation and remote access

The device communicates wirelessly via Wi-Fi, enabling remote access to data using a mobile application (Android and iOS) or a web browser. This makes it possible to control energy consumption from anywhere in the world. The F&F Polish cloud guarantees data security and stable system operation. Mounting on a 35 mm rail is simple and intuitive, and the miniature current transformers do not require intervention in the power cables during installation – just clamp them onto the measured conductors.

Safety first

The kit also includes a signaling lamp LK-BZ-3 with protection, which protects against the effects of current increase above the permissible value. It is equipped with 5x20 mm fuse links providing safe disconnection of the circuit in the event of a failure or maintenance work. The kit meets safety standards and is made of high-quality materials, which guarantees reliable operation for a long time.

• Measurement accuracy: The meter is characterized by an accuracy of 1%, and the measuring transducers 0.5%.
• Measurement range: Transducers with a primary current of 40 A allow monitoring of installations with high energy demand.
• Compatibility: The kit works with 3-phase, 4-wire installations with a supply voltage of 3x230/400 V AC (-25%÷15%).
• Easy integration: The device can be easily integrated with other elements of the wireless home automation system FOX.
• Dimensions: Compact dimensions (2 modules - 90 x 35 x 85 mm with antenna) allow mounting in a limited space of the switchgear cabinet.
