Single phase electric power/energy calibrator with power quality functions for calibration and testing of grid measuring appliance like power meters, power transducers or power quality analysers. Terminals 2 and 3 are inactive.

M133C is electric AC/DC power and energy calibrator for calibration of power meters, power transducers, power quality analysers and generally all kinds of power measuring devices. AC voltage, current, power and energy functions have calibrated phase shift in frequency range from 15 Hz to 1 kHz with resolution as good as 0.001 Hz. Built-in 5½ process multimeter for transducer calibration is standard part of every M133C calibrator.

Power quality functions

Four different distortion functions are available in M133C calibrator: Harmonic distortion with up to 63 harmonic products, interharmonic distortion up to 5000 Hz, amplitude modulation using symetrical sine or square wave envelope and finally dip/swell amplitude modulation using custom square wave envelope. Modulation frequency can be set in range from 0.001 Hz to 50 Hz, maximum modulation depth is 30 %.

Calibration versatility

M133C is more than just a sophisticated power source. Using built-in process multimeter, both transducer inputs and outputs can be handled by the M133C at the same time so you can calibrate it more easily, using no other calibration equipment. Floating current output can be connected directly with voltage output to allow for 3-wire power meter calibration. One calibrator, many applications - saving your time, space and costs.
