The Model MC133C is a compact single housed three phase electric power/energy calibrator. It can supply the
device under test with precision one phase AC voltage and current with calibrated phase shift along with
DC voltage and current. Output voltage can be set in five ranges up to 280V and output current in six
ranges up to 30A.
Simulated electric power can be set independently for each phase. Frequency can be set from 15Hz to 1kHz
with resolution 0.001Hz to 0.01Hz. The MC133C Calibrator is equipped with 5 1/2 digital DC meter with
DC ranges of 20mA and 10V for direct calibration of various types of power transducers.
MC133C calibrator offers two types of defined distortion of its main sinusoidal output signal. The first
distortion is based on adding defined amounts of harmonic or inter-harmonic spectral components up to
5kHz. The second type of distortion is based on amplitude modulation of its output sinusoidal signal
by a sine or square-wave modulation over the frequency range from 0.001Hz to 50Hz. Maximum depth of modulation
Using a supplied cable adapter the current outputs can be joined together offering single phase current to
