Yokogawa WT1806E Precision Power Analyzer (-5A0 -50A6 -HE -D /EX6 /G5 /PD2)

When evaluating complex power electronics, EV powertrains, solar inverters, and high-efficiency motor drives, the Yokogawa WT1806E provides uncompromising accuracy and measurement flexibility. Built with a guaranteed basic power accuracy of ±(0.05% of reading + 0.05% of range), this 6-channel precision power analyzer allows simultaneous sampling across multiple voltage and current inputs at 2 MS/s (16-bit resolution).

This specific configuration features 6 direct 50A current input elements (-5A0 -50A6) along with factory-installed performance options—including Harmonic Measurement up to the 500th order (/G5), External Sensor Inputs for all 6 channels (/EX6), and an Internal DC Power Supply for AC/DC current sensors (/PD2). Combined with an 8.4-inch XGA screen and robust power integration modes, the WT1806E is the premier benchmark for industrial power quality and efficiency characterization.
