Digital Panel Meter Description:
Functions and applications:
Intelligent digital meters suitable for electricity grid, automated
control system for voltage, current, active power, reactive power,
apparent power, power factor and frequency measurement of
electrical parameters from digital (LED) or liquid crystal (LCD)
display directly. Has shown an intuitive, high precision, stable
performance and strong isolation, anti-vibration and so on. A
variety of optional extensions, including RS-485 communications,
digital input, digital output and analog output and other
quantitative relations, rich dimensions can be easily replaced
pointer instrument.
