Main Features

• High Accuracy: Power output accuracy class selectable among 0.1/0.05/0.02, voltage and current accuracy class selectable among 0.1/0.05/0.02, harmonic output accuracy 0.1% RG, frequency resolution 0.002Hz, suitable for AC electrical quantity detection and calibration.
• Wide Output Range: Accurate output range 30~420V (600V), 50mA~20A (120A), fundamental frequency 40~65 (400) Hz, can be used as standard voltage source, standard current source, standard power source, meeting the detection and calibration needs of AC voltmeters, ammeters, power meters/energy meters, and other AC measuring devices.
• Automatic Range Switching Across Full Output Range: Voltage and current automatically switch to appropriate output ranges throughout the entire output range to ensure accuracy indicators across the full output range.
• Superimpose up to 49 Harmonics: Voltage and current can output fundamental wave superimposed with harmonics, capable of outputting any single or multiple harmonics from 2nd to 49th order.
• Phase and Frequency Variation: Each phase output is independent, allowing separate control of amplitude, frequency, and phase for each phase, flexible and convenient.
• Parallel Current Expansion: Three-phase currents can be paralleled to output as single-phase current, increasing output current range by up to 3 times, flexible usage.
• Low Load Regulation: Power amplifier uses hardware closed-loop deep negative feedback technology, adjustment time from no load to full load is at millisecond level, typical load regulation less than 0.01% RD.
• Low Waveform Distortion: Each cycle is fitted with 50,000 points, enabling high-order harmonic output; peers use 360~3600 points, typical distortion 0.03%, peers 0.2%.
• High Annual Reliability: Output annual stability typical value is 60 PPM/year, no need for annual recalibration, ensuring long-term device accuracy.
