Multifunctional Power Meter
The MRD-B multifunctional power meter offers a reliable electrical parameter metering solution, and it is characterized by easy installation, simple wiring, convenient maintenance, in-place programming and other properties.
Function
This multifunction power measuring device is able to calculate active energy, reactive energy, harmonic content and many other commonly-used electrical parameters, and it also provides other functions, like digital communication, off-limit alarm, switch status monitoring, pulse output and analog output. This fully interprets its name: multifunctional power meter.
Application
Our digital power meter could be installed in substations, power distribution networks, intelligent buildings, switch cabinets, energy management systems, industrial automation systems, etc.
