The Yokogawa 760302 WT3000 Precision Power Analyzer is the ideal measurement solution for applications such as product efficiency testing, engineering, R&D work on inverters, motor drives, lighting systems and electronic ballasts, UPS systems, aircraft power systems, transformer testing and other power conversion devices. Basic power accuracy of ± 0.02% of reading, DC and 0.1 Hz to 1 MHz measurement bandwidths, with two input elements, the WT3000 provides higher-accuracy measurement for inverter I/O efficiency. Features. Large, 8.4-inch LCD and the Range Indicator LEDs. 50 ms Data Storing Interval. Available GP-IB, Ethernet, RS-232 and USB. Specifications. Basic Power Accuracy: ±(0.02% of reading + 0.04% of range). Frequency Range: DC, 0.1 Hz to 1 MHz. Power factor influence when cos phi=0: 0.03% of S (S is reading value of apparent power)(phi is phase angle between voltage and current). Current Range Direct Input: 0.5/1/2/5/10/20/30 A, 5m/10m/20m/50m/100m/200m/500m/1/2 A (when crest factor is 3). Current Range External sensor Input: 50m/100m/200m/500m/1/2/5/10 V (when crest factor is 3). Guaranteed accuracy range for voltage and current ranges: 1% to 130%. Main measurement parameters: Voltage, current, active power, reactive power, apparent power, power factor, phase angle, peak voltage, peak current, crest factor. Motor Version provides analog or pulse signal from rotating sensor and torque meter can be input, and allows calculation of torque, revolution speed, mechanical power, synchronous speed, slip, motor efficiency, and total efficiency in a single unit.
