The SDM230 series is a series of multi-function single-phase electricity meters in 2P size. It measures active energy, reactive energy, current, voltage, power, power factor, frequency, demand, etc. The units support direct connection of max. 100A, saving costs and avoiding the trouble of connecting external CTs. Two pulse outputs and 1 communication port (Mbus/Modbus) are available for remote monitoring.
The pulse output can be configured for:
- Import + Export = total kWh
- Export - Import = total kWh (net)
- Import = total kWh
- Export = total kWh
- A RS-485 Modbus RTU or M-bus EN13757-3 communication port is available. The communication parameters are password protected in the setup mode. The SDM230-2T version can measure energy from two different sources and functions as a dual meter.
