GF303D portable 3 phase ac Electrical Power Calibrator with 500v voltage and 120a current source
GF303D portable 3 phase ac Electrical Power Calibrator is suitable for power department, measuring department, quality control department, research units, and institutions of higher learning, and electric energy meter, power distribution terminals, power supply management, load control, power quality, reactive power compensation device and the production of enterprise etc.
GF303D 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 40 Hz to 70Hz with resolution as good as 0.001 Hz.
The GF303 AC Power Calibrator is equipped with RS232 PORT as standard communication interface to control external devices remotely. Power Factor Validation Power factor is an important element when users judge the efficiency of a device.
In the Power Calibration mode, the GF303D can be used as a source to calibrate DC and single-phase AC watt meters, power analyzers, and energy meters. In this mode, the output voltage can be set up to 500V, the output current up to 120A, and the power factor from -1.0 to +1.0 lead/lag in the frequency band from 40Hz to 70Hz.
FEATURES
- To set up and take the load regulation of voltage, current, phase angle ,frequency and power factor etc; as a large current source, voltage source and power source
- To set 2 ~ 51 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output
