The Yokogawa Electric 2533, Digital Power Meter, that is an outstanding solution to accurate power measurement of distorted waveforms with simple and fast flat-key controls. The Yokogawa 2533 is a 3-phase input, AC or DC Digital Power Meter. The 2533/E23 is designed for measuring a variety of configurations from single phase/2 wire, up to 3 phase/4 wire power applications. It provides simultaneous display of 3 measured values; voltage, current, & power in each phase or total power, apparent power, reactive power, or power factor. It also provides true rms measurements of square, triangular, and distorted waveforms. Maximum input is 600 VAC at 20 A. IEEE-488 interface is standard. Specifications Rated Input: Voltage Ranges: 30/60/150/ 300/600 V Current Ranges: AC: 0.5/1/2//5/10/20 A DC/AC: 1/2/5/10/20 A Frequency Ranges: AC: 10 Hz to 30 kHz DC/AC: DC, 10 Hz to 30 kHz Crest Factor: AC Voltage: Max. 2 AC Current: Max. 3 DC/AC Voltage: Max. 2 DC/AC Current: Max. 3 or 50 A (peak) Principle: Voltage: Change of mean value rectification and true RMS by LOG-anti LOG Current: True RMS by LOG-anti LOG PWM time division multiplication Accuracy: ±0.1% of reading +0.1% of range Influence By Power Factor: Within 50/60 Hz ±0.5% of reading at cos Ø=0.5 Features Simultaneous Display of 3 Measured Values High Precision Wide Band of DC 10 Hz to 30 kHz Abundant Computing Functions are Incorporated PT and CT Sealing Analog Output is Standard Equipment
