M-133 / M-133i Power/energy calibrator is one phase calibrator of electric power and energy.
M-133 contains option for generation of distorted signals with defined parameters. The option application field
is focused to the field of calibration of quality of energy analyzers. One phase can be extended to three phase
system using additional amplifiers M-133f.
M-133i is delivered without the option of harmonic/interharmonic functions.
Basic feature of the device is precise simulation of DC and AC electric power and energy in voltage range to 280V
and in current range to 30 A. In AC electric power mode phase shift between voltage and current channel can be set in
range 0º to 360º. Best accuracy of simulation is 0.05%. Calibrator offers high burden current of voltage output of
several hundreds mA and compliance voltage of current output up to 5Vrms. Current range can be extended using
Option 140-50 50 turns current coil up to 1000 A.
M-133 calibrator is equipped with special functions for power line voltage analyzers testing. It can generate calibrated
harmonic and interharmonic distortion, fluctuation harmonics, flickers, ramp signals and others. User interface offers
simple and user convenient programming of output signal parameters.
The calibrator can be extended to four-wire three-phase system using two additional „slave“ amplifiers M-133f.
