This product is a µP-based indicator with manual or automatic scrolling of system and single phase functions, which can measure kW, kVAr, PF, kWh, kVArh, I, V∆avg, VL1-N, VL2-N, VL3-N. It can also measure distorted waves (voltage/current) of TRMS, select all configuration functions by the built-in keypad, and protect programming parameters with passwords. The front protection level is IP 40, and it has standard pulse output and optional serial RS 422/485 output, supporting MODBUS and JBUS protocols.
This manual describes the WM2-DIN power analyzer, covering its input and output specifications, measurement functions, and configuration options. It includes details on the front panel, keypad operation, and programming features such as password protection and data logging.
The document also provides wiring diagrams for single‑phase and three‑phase connections, terminal board layouts, and safety information such as protection class, operating temperature, and compliance standards. Technical data like sampling rate, display resolution, and power consumption are listed for reference.
