M133i Low-cost Power & Energy Calibrator Power and energy calibrators  Meatest


  • Voltage “phase-neutral” 1 V to 280 Vdc / 300 mA, 1 V to 600 Vac
  • AC voltage “phase – phase” in the 3phase system 2 V to 1200 V
  • DC/AC current 30 mA to 30 A / 5 V, accuracy 310 ppm
  • Power factor setting -1 to +1
  • Frequency range 15 Hz to 1 kHz
  • Simulated electric power up to 8.4 kVA (420 kVA with option 140-50)
  • Built-in process multimeter
  • GPIB & RS232 interface



Model M133i is one phase electric power/energy calibrator. The unit creates also master unit in three-phase power/energy calibartion systems. It can supply unit 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 600 V and output current in six ranges up to 30 A. Simulated electric power can be set independently in each phase. Frequency can be set in range from 15 Hz to 1 kHz with resolution 0.001 Hz to 0.01 Hz. Calibrator is equipped with 5 1/2 digital DC meter with DC ranges 20 mA or 10 V for direct calibrating of various types of power transducers.

M133i offers only SIN wave output signals. Harmonics, interharmonics, modulation and dip/swell modes are not available in this model. Ranges and accuracies of M133i version sinus output are identical to M133 model features.

Three-phase electric power/energy calibration system can be optionally built using one M133i master unit and two M133if slave units. The slave units contain power stages of each additional phase output. They are fully controlled from master unit via rear panel special interface. Maximum output voltage between two phase voltages is 1200 VAC. Current outputs can be joined together offering total range to 90 A AC/DC.
