The document describes the CARLOGAVAZZI WM30, a modular power analyzer designed for single-, two-, and three-phase electrical systems. The system consists of a main unit with an LCD display and touch keypad, which can be expanded with up to three accessory modules: digital outputs, analogue outputs, or communication interfaces.
Key features include the measurement of active and reactive energy, harmonic distortions (up to the 32nd harmonic), and load operating hours. The analyzer supports various communication protocols such as Modbus RTU/TCP/IP, BACnet IP/MS/TP, and Profibus DP V0 via optional modules. It is suitable for applications in automation, building management, and energy monitoring.
