Product Overview

The YD6600-N integrates measurement, monitoring, display, and digital communication in one instrument. It supports measurement of multiple electrical and energy quality parameters including voltage, current, active/reactive/apparent power, power factor, frequency, harmonics, and total energy. It is suited for applications in industrial, IoT, telecommunications, and electric power sectors.

With wide voltage compatibility (AC 3×220/380V or 3×57.7/100V) and rated current of AC 3×5(6)A, the YD6600-N is engineered for stable operation across various conditions. The meter’s panel-mounted size of 90 × 90 mm allows for easy installation in control cabinets.
