Yokogawa WT3004E Precision Power Analyzer

The Yokogawa WT3004E Precision Power Analyzer is the benchmark for energy efficiency measurement and a reference for calibrating power-measuring instruments in standards laboratories. Yokogawa WT3004E analyzers are ideal for the design and testing of solar inverters, motor drives, lighting systems, uninterruptible power supplies, transformer testing, aircraft power systems, and other power conversion devices. With basic power accuracy of ±0.01% reading, DC and 0.1 Hz-1 MHz measurement bandwidths, and up to four input elements, the WT3004E provides high-accuracy measurement of I/O efficiency.
