Model M133C is compact one-housing three phase electric power/energy calibrator. It can supply unit under test with one phase accurate AC voltage and current with calibrated phase shift or DC voltage and current. Output voltage can be set in six ranges up to 600 V and output current in six ranges up to 30 A. Simulated electric power can be set independently in each phase. Frequency can be set in range from 15 Hz to 1 kHz with resolution 0.001 Hz to 0.01 Hz. Calibrator is equipped with 5 1/2 digital DC meter with DC ranges 20 mA or 10 V for direct calibrating of various types of power transducers.

M133C calibrator offers two types of defined distortion of main sinusoidal output signal. The first distortion is based on adding defined amount of harmonic or interharmonic spectral components up to 5 kHz. The second type of distortion is based on amplitude modulation of output sinusoidal signal by sin or squarewave modulation signal in frequency range from 0.001 Hz to 50 Hz. Maximum depth of modulation is 30 %.

Using supplied cable adapter the current outputs can be joined together offering one phase current range to 90 A AC/DC.

M133 control panel facilitates setting of power energy calibrators series M133. It is possible to set all three phase channels and also waveforms of individual voltage (current) outputs. Setting of harmonic / interharmonic components, modulation and Dip/Swells is displayed in simple chart.
