Our products include smart power distribution systems, power quality monitoring & analysis management system, and temperature, humidity & vibration monitoring & management systems. We also offer wireless vibration measurement systems, online power quality analyzers, smart low voltage motor protection controllers, electricity transmitters, and electronic active / reactive energy meters. MPM8000 is a powerful multi-function power meter with modular design, which can be applied for monitoring and controlling the electrical system. MPM8000 can measure and analyze real time data, such as U, I, P, Q, S, COS, F, kWh and kVAr. MPM8000 has RS-485 communication port, 2 energy pulse output (include active energy & reactive energy), max/min data record, and SOE event record. MPM8000 can extend functions by choosing the external optional modules such as harmonic analysis, 8 remote signals on/off mode, and programmable 4 analog outputs. The multi-tariff function allows the user to measure energy in any interval.
