Multi functional power meter, full capacity power quality analysis, UL certification

The APM5 series network power meter (hereinafter referred to as the meter) is designed according to IEC international standards and has functions such as full power measurement, power statistics, power quality analysis (including harmonics, interharmonics, flicker), fault recording (including voltage rise and fall interruption, impulse current recording, etc.), event recording, and network communication. It is mainly used for comprehensive monitoring of power supply quality in the power grid. This series of instruments is equipped with feature rich DIDO modules, AO modules, wireless communication modules, and leakage temperature measurement modules, which can flexibly achieve full power measurement and switch status monitoring of electrical circuits.

The instrument provides asynchronous half duplex RS485 communication interface, using MODBUS-RTU protocol, and various data information can be transmitted on the communication line. It is recommended to use shielded twisted pair cables for communication connections, with a cross-sectional area of no less than 0.5mm per core?. When wiring, communication lines should be kept away from strong electrical cables or other strong electric field environments
