Modern digital single-phase multifunctional electricity meter that measures up to 100 A direct load. The SDM230modbus has 15 measured parameters and 4 different kWh measurement modes, which were designed with the development of photovoltaics such as solar and battery storage in mind. The pulse output can be configured for: • Import + Export = total kWh • Export - Import = total kWh (net) • Import = total kWh • Export = total kWh Communication port RS-485 Modbus RTU or M-bus EN13757-3 is available. The communication parameters are protected by a password in the setting mode. The SDM230-2T version can measure energy from two different sources and works as a dual meter. Basic specifications • Nominal voltage (Un): AC 120 or 230 V • Working voltage range: 80 to 120% of nominal voltage (Un) • Frequency: 50/60 Hz • Current (Ib): 10 A • Max. current (Imax): 100 A • Isolation capability: 4 kV AC voltage withstand for 1 minute + 6 kV impulse voltage resistance - 1.2 µS
