Power & Energy Calibrator Power quality and energy functions Three and single phase versions Phase accuracy 0.01º, frequency range 15 – 1000 Hz AC power up to 3x 18 kVA, DC up to 25.2 kW Optical scanning head, built-in multimeter Floating current outputs for 3-wire power meters Current coil for clamp meters up to 2250 A M133C is electric AC/DC power and energy calibrator for calibration of power meters, power transducers, power quality analyzers and generally all kinds of power measuring devices. Full version of M133C calibrator can generate four types of power distortion: harmonic up to 50 products, interharmonic up to 5 kHz, amplitude modulation using symmetrical sine or square wave envelope and finally dip/swell amplitude modulation using custom square wave envelope. All the parameters including distortion can be set independently for each phase. 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 outputs can be connected directly with voltage outputs o allow for 3-wire power meter calibration. One calibrator, many applications – saving your time, space and costs.
