MC133c-3F Three-Phase Compact AC Power Calibrators
The MC133c-3F model are compact, one-housing, three phase electric, ac power calibrators.
Description
The MC133c-3F model are compact, one-housing, three phase electric, ac power calibrators. It can supply the device 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 five ranges up to 280V and output current in six ranges up to 30A.
Simulated electric power can be set independently in each phase. Frequency can be set in range from 15Hz to 1kHz with resolution 0.001Hz to 0.01Hz. AC Power Calibrator equipped with 5 1/2 digital DC meter with DC ranges 20mA or 10V for direct calibrating of various types of power transducers.
Using supplied cable adapter the current outputs can be joined together offering one phase current range to 90A AC/DC.
MC133c-3F offers only SINE wave output signals. Harmonic and inter-harmonic distortion is not available in this model.
