Three-phase AC DC Calibrator factory
A flexible instrument used for calibration and testing across several industries is the KS833 Three-phase AC DC Calibrator (0.05 class). It has three AC voltage sources with a combined accuracy of 0.05% (3x900V@3x25VA), three AC current sources with a combined accuracy of 0.05% (3x30A@3x25VA), and a three-phase harmonic standard power with a combined precision of 2-31th orders (0.1% accuracy).
