SHARE

The CMM-41 Multifunction Electrical Measurement Center is a comprehensive solution designed for advanced energy monitoring and management. This compact unit, featuring dimensions of 72×72 mm, is suitable for integration into space-constrained environments such as cabinet front panels. It measures all electrical network parameters along with bidirectional energy, making it ideal for diverse applications ranging from industrial machinery and smart buildings to public utilities and mining operations. The device supports TN, TT, and IT networks and can operate both in single-phase and three-phase configurations. It features high accuracy with voltage and current measured to 0.2% and active energy to class 0.5s standards. Equipped with an RS485-Modbus communication port, the unit supports efficient data exchange and real-time updates every second. It ensures operational safety with isolation up to 2kV and is compliant with IEC61010-1 standards, providing reliable performance in harsh conditions with an IP54 protection rating.
