MEM-21
Energy monitor 3F+N
MEM-21 is an electricity monitor that allows you to measure energy, current, voltage and power on each of the three phases. This device can be used as a monitor of energy consumed, produced or both at the same time. Therefore, it can be easily used as a submeter in photovoltaic (PV) installations.
– measurement of energy consumed, produced or both at the same time,
– measurement of network parameters divided into each phase,
– cooperation with the EFC-01 controller,
– measurement carried out using transformers with a maximum current of 100 A,
– signaling the presence of voltage on individual phases, collecting data on energy consumed in the cloud + data export to an xls file,
– possibility of remote software update,
– measurement of network parameters divided into each phase.
