Description:
The WM15 is a panel‑mounted power analyzer for single‑, two‑, and three‑phase systems. It measures main electrical variables, harmonic distortion, active/reactive/apparent energy, and load operating hours. The backlit matrix LCD display shows instantaneous values and a bar graph of currents. The unit can be self‑powered (up to 415 V L‑L) or use an auxiliary supply (up to 600 V L‑L). Depending on the model, it offers a static pulse/alarm output, RS485 Modbus RTU, or M‑Bus communication. The MID‑certified version (Class B kWh) is suitable for fiscal metering. Configuration is via the keypad or using UCS software/OptoProg interface. The device is compliant with IEC/EN61557‑12 (active power and active energy) and IEC/EN62053‑21/22 (energy measurement). An optional high‑accuracy version (Class 0.5S) is available.
