With the growing focus on generating and converting power more efficiently, the use of renewable energy sources like solar and wind is expanding. Alongside these trends, rapid advances in electric vehicles and energy-efficient technologies make precise measurements essential to detect even the smallest energy losses. Whether analyzing multiphase inputs during motor and drive design or meeting stringent efficiency standards for photovoltaic inverters, the WT1800R high-performance power analyzer offers engineers a precise and reliable tool to measure power, quality, and efficiency.

The WT300E series digital power analyzer provides extremely low current measurement capability down to 50 micro-Amps, and a maximum of up to 26 Amps RMS. This instrument is ideal for engineers performing stand-by power measurements, Energy Star®, SPECpower and IEC62301 / EN50564 testing, battery charger and other low-level power measurements.

The WT500 Power Analyzer excels at single- and three-phase power measurements. The instrument has a basic power accuracy of 0.1%, maximum inputs of 1000 V, 40 A, and a measurement bandwidth of DC to 100 kHz.

Experience unmatched precision with the Yokogawa WT5000, the world’s leading precision power analyzer. Engineered for demanding electrical and mechanical power and efficiency testing, the WT5000 provides multi-channel measurements, advanced harmonic analysis, and intuitive operation through user-friendly software and a responsive touchscreen. With seven swappable input elements, four motor channels, and approval for SPEC Power® and IEC standards, the WT5000 is an ideal platform for high-accuracy power measurements.
