Digital Power Meter

SPM33 Digital Power Meter Multifunction Power Meter SPM33 three phase multi-Function power meter, mainly apply to low Voltage Distribution System, which voltage below AC400V (L-N), it can through RS485/ Modbus communication to manage instrument of network, and achieve automatic control.The main characteristics of SPM33 are as follows:Real-time parameter measurement,Demand measurement ,2 active status inputs,2 relay outputs (optional),Alarm function,Up to the 31st harmonic measurement, phase voltage and current harmonic content (2 to 32), THD,1 RS485 communications, Modbus – RTU protocol,Phase sequence adjustment ,Support Dual-source kWh measurement etc
