APM-4MJ Advanced power meter features
Power Quality Monitoring
The APM-4MJ Advanced power meter monitors harmonic distortion, voltage sag & swells, frequency variations, voltage, current unbalance factors, and other potentially harmful power events to prevent power quality issues. Besides, it can help you analyze energy power quality through harmonic analysis, event logging, and waveform capture. The harmonic analysis of APM-4MJ multi-function meter supports up to 31st individual harmonics. The waveform recording capabilities show you the waveform of voltage current, voltage sag or swell, over current, or switch status. The event logging can be saved in the 128MB memory.
Max Demand Measurement & Record
The APM-4MJ advanced electricity meter supports current and power max demand measurement. The max demand measurement is common for industrial use to help you manage electricity consumption, reduce costs, and improve efficiency.
Compatible for Any Electrical System
The APM-4MJ advanced power meter is built in RS485 and Ethernet is optional, which makes this multifunction power meter support multi-protocol. Besides, the different energy meter wiring is supported so it is compatible with 1 phase 2 wire, 2 phase 3 wire, 3 phase 3 wire, and 3 phase 4 wire systems.
Industrial High Accuracy
The AMP-4J multifunction advanced power meter monitors all essential measurement parameters with class lass 0.5S/0.5 per IEC 62053-22/ANSI 12.20. It is an ideal multifunction metering solution for industrial energy metering projects, such as HV & LV Switchgear Panels, Plant automation and monitoring systems, Motor Control Center (MCC) Panels, Power Control Center (PCC) Panels, Process Control, Industrial Control Panels, industrial automation, power quality monitoring, etc, and offer precise, reliable data in these applications
