Tax included
The electricity meter is an advanced measuring device that allows for precise monitoring of power consumption in single-phase installations. Thanks to its compact design and mounting on a standard DIN rail TS-35, it is ideal for both home and industrial distribution boards. The main advantage of this model is the clear LCD display with blue backlight, which enables easy data reading even in poorly lit areas. The device is characterised by a high measurement accuracy of 0.001 kWh, which allows for a very detailed analysis of energy costs. A robust housing made of high-quality plastic ensures durability and safety of use for years.
An additional advantage is the pulse output, which allows for the connection of external counting systems, making this meter an excellent component of smart home or building automation systems. The product complies with rigorous European standards, which guarantees its reliability and precision. By choosing this meter, you gain full control over electricity expenses, which promotes savings and an ecological lifestyle. A long, 5-year manufacturer warranty confirms the highest quality of this measuring instrument. The device is resistant to difficult working conditions in a wide temperature range from -25 to 55 degrees Celsius. The IP51 protection class protects against dust and dripping water, which increases reliability in control cabinets. The meter is extremely simple to install, occupying only one module in the distribution board, which allows for optimal space utilisation.

Software and logic
The meter software is based on an advanced algorithm for real-time analogue-to-digital signal processing. The microcontroller operating system manages precise sampling of voltage and current, calculating active power taking into account phase shifts. The graphical interface on the 5+2 LCD display provides a clear presentation of data on total energy consumption in kilowatt-hours. The software also controls the pulse output logic (1000 imp/kWh), which allows for integration with BMS (Building Management System). Built-in non-volatile EEPROM memory ensures that all accumulated measurement data is safe and will not be lost in the event of a main power failure. The system also has an auto-calibration and internal error monitoring function.
