Tthree-phase LCD harmonic multi-function meter

This three-phase LCD harmonic multi-function meter with Profibus port is engineered for power quality monitoring in industrial power distribution systems. It can measure multiple electrical parameters including voltage, current, frequency, active/reactive power, apparent power, power factor, energy consumption and harmonic values.

It adopts a high-contrast LCD screen to display real-time power data clearly. Supporting Profibus and RS485 dual communication interfaces, it realizes remote meter reading and continuous online data monitoring. This panel-mounted meter features high measurement accuracy of class 0.5, simple installation and stable performance. It is widely used in industrial automation, building power distribution and energy management systems, helping users detect harmonic distortion and achieve precise power monitoring and energy analysis.
