Single-phase electricity energy meter, WI-MEF-1 40A WI-MEF-1-40

Intelligent energy consumption monitoring for your home and business

The WI-MEF-1-40 electrical energy monitor is an advanced device designed for precise measurement of electrical energy consumption in single-phase installations. Thanks to Wi-Fi communication, consumption data is available remotely, enabling effective energy management and cost optimization. The device is ideal for both demanding home users and professionals involved in electrical installations and photovoltaics.

Precision and reliability of measurement

The WI-MEF-1-40 meter is characterized by high measurement accuracy – 1% for the meter and 0.5% for the measuring transducers. The current transformer with a range of 40A allows monitoring of loads with different power, and the wire diameter up to 10 mm ensures compatibility with most installations. The meter constant is 1000 impulses per kWh, which guarantees precise readings of energy consumed. The device operates in the power supply voltage range of 230 V AC (with a tolerance of -25% to +15%) and frequency of 50/60 Hz.

Easy installation and remote access

The device is easy and intuitive to install – it is mounted on a standard 35 mm rail and takes up only 1 module (18 mm). Wi-Fi communication enables remote access to data via a mobile application or web browser, allowing you to monitor energy consumption, detect irregularities and analyze trends in real time. No need to physically read the meter saves time and convenience. The kit includes a miniature current transformer, which enables non-invasive installation without the need to interfere with the power cables.
