The M133C three-phase or single-phase power/electricity calibrator with power quality function is used 

for calibration and testing of grid measurement equipment such as power meters, power sensors, or power quality analyzers. 

AC voltage, current, power, and energy functions have calibrated phase shifts in the frequency 

range of 15Hz to 1kHz with a resolution of up to 0.001Hz. 

Analog power (including power quality function) Can be set independently in each phase of the voltage and current signals. 

The M133C calibrator has a built-in 5½ programmable multimeter for sensor calibration.

1. Power quality and energy function.

5  Floating current output for 3-wire power meter calibration.

6. Single-phase calibrator can also be used to form a three-phase calibrator.

7. Calibration of parameters such as voltage, current, power, capacity, P.F and phase angle.

8. RS232 and GBIP interfaces available.

9. Built-in programmable meter function.

10. DC output voltage range: 1 to 280 V.

11. AC output voltage range: 1 ~ 600 V.

12. DC output current range: 5 mA ~ 30 A.

13. AC Output Current Range: 5 mA ~ 30 A.

14. DC power calibration range: 5 mW ~ 8.4 kW.

15. AC power calibration range: 5 mW ~ 18 kW.

16. P.F setting range: -1 to +1.

17. Frequency Range: 15 Hz ~ 1 kHz.

Power Quality Functions

The M133C calibrator has four different distortion functions: harmonic distortion up to 50 harmonics, interharmonic distortion up to 5000 Hz.

Amplitude modulation using a symmetrical sine or square wave envelope, 

and finally step-down/step-up amplitude modulation using a customized square wave envelope. 

The frequency modulation can be set from 0.001 Hz to 50 Hz with a maximum modulation depth of 30%, 

and all distortion parameters can be set independently for each phase.

Versatile Calibration

The M133C calibrator is more than just a complex power supply. 

With the built-in programmable multimeter, sensor inputs and outputs can be processed simultaneously by the M133C, 

so you can calibrate more easily. The floating current output can be directly connected to the voltage output for three-wire power meter calibration. 

One calibrator, many applications - saving your time, space and money.
