Business solutions for capturing high-speed sampling, wide frequency range, and waveform analysis, with multiple input elements, is one way Yokogawa continues to provide the quality products your applications require.
Experience unmatched precision with the Yokogawa WT5000—the world’s leading precision power analyzer. Engineered for the most demanding electrical and mechanical power and efficiency testing, the WT5000 offers multi-channel measurements, advanced harmonic analysis, and intuitive operation through its user-friendly software and responsive touchscreen. With seven swappable input elements, four motor channels, and approval for SPEC Power® and IEC standards, the WT5000 is the ultimate tool for high-accuracy power measurements.
The WT3000E is the world’s highest accuracy Power Analyzer. The basic power accuracy is 0.01% of reading + 0.03% of range. It is the enhanced version of the industry standard WT3000. Along with high accuracy it provides a broad bandwidth of DC, and 0.1Hz to 1 MHz. The high measurement accuracy will provide engineers with the test data needed to evaluate power consumption and energy loss more precisely.
The WT1800E is a flexible and reliable power analyzer that guarantees power accuracy of 0.05% of reading plus 0.05% of range. It is capable of harmonics analysis up to the 500th order of a 50/60 Hz fundamental frequency. With up to 6 input channels, a wide range of display and analysis features, and PC connectivity, the WT1800E can handle broad variety of power efficiency and harmonic analysis requirements.
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 WT500 Power Analyzer excels at single-phase and three-phase power measurements. Standard features include a color TFT display and USB interface for communications and memory. The instrument has a basic 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.
The PX8000 is the world's first precision power scope, bringing oscilloscope-style time-based measurement to the world of power analyzers. With up to four channels, it can perform standard multi-phase power measurements. These measurements exist alongside oscilloscope-specific features such as cursor-based specific time period measurements to enable analysis of waveforms with transient components.
The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, easy to use navigation screens and bluetooth and SD cards for communication and data logging. These features enable user-friendly power consumption and power quality measurements in the field that conform to IEC61000-4-30 Class S. This standard dictates that two measuring instruments of similar rating must measure within some percentage of each other when exposed to the same signal.
