Smart Digital Display Electric Power Meter is suitable for the measurement of voltage, current, active power, reactive power, apparent power, power factors, frequency and four limiting electric parameters in power grid and automation control system. It is directly displayed by digital tube (LED) or liquid crystal (LCD) with the advantages of intuitive display, high precision, stable performance and separation and vibration resistance. Various extended functions are available, including RS-485 communication, switching input, switching output and analog output, etc. Rich shape and size can easily replace the pointer instrument.
The product is simple in structure, elegant in appearance, stable in performance and convenient in installation, using Pluggable type terminals.
