F-PEM100 Multifunction Power Meter, Power Quality Analyzer

The F-PEM100 series of environmentally friendly electricity intelligent monitor

terminals are mainly used to measure the three-phase active energy of the low-

voltage network. It has RS485 communication and LoRa 470MHz wireless

communication functions, which are convenient for users to monitor, collect and

manage electricity consumption. It can be flexibly installed in the distribution box

to realize the sub-item electric energy measurement, statistics and analysis of

different areas and different loads.

It is mainly used in enterprises that cause pollution to the environment, and is

installed on the electricity circuit of pollution-producing facilities and pollution

control facilities for electricity consumption monitoring.
