Nemo 96 HDLe MF96412 Flush mounting multifunction for low voltage

THÔNG TIN CHI TIẾT

Nemo 96 HDLe MF96412 IME
Connection via CT for single and three-phase network, 3 or 4-wires.
Phase sequence correction, diagnostic
Can be accessorised with an additional modules.
It makes available active or reactive energy counting of the pulse output
to integration of consumption supervision systems.
For supervision systems, through the model with output RS485
communication ModbusRTU, you can transmitted on the network main
electrical parameters in addition to the energy consumption.
