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.

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.

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 WT1500 Precision Power Analyzer brings Yokogawa's trusted power measurement performance to production and automated test systems. Combining ±0.038% total power accuracy, direct measurement up to 2000 V, 2 MHz bandwidth, and a compact 2U rack-mount design, it delivers the precision, connectivity, and scalability required for demanding power electronics, motor, and system-level testing.

With up to four power and four motor channels per unit, multi-unit synchronization, and ATE-ready interfaces including CAN/CAN FD, UDP, IEEE 1588, and remote control, the WT1500 integrates easily from a single test station to large multi-channel systems.
