Product Overview: The power meter features precise measurement of power parameters, monitoring and analysis of power quality parameters, power energy statistics, over-limit alarm, maximum value recording, and event sequence recording. Through the I/O module, it realizes the monitoring of the status of on-site equipment, remote control, and alarm output. The power meter provides standard communication interfaces and can choose dual communication network redundancy. It also offers power pulse output and 4-20mA analog output functions, which can drive analog and logic quantity preset alarms. The large-screen liquid crystal display interface enables users to easily obtain power parameters.
