Portable Three Phase AC Voltage and Current Source GF303D GFuve

Back

The model GF303D three phase power source is electric AC voltage, current and power calibrator for calibration of power meters, power transducers, power quality analyzer, current meter, voltage meter and generally all kinds of power measuring devices.

Description

The model GF303D three phase power source is electric AC voltage, current and power calibrator for calibration of power meters, power transducers, power quality analyzer, current meter, voltage meter and generally all kinds of power measuring devices. AC voltage, current, power functions have calibrated phase shift in frequency range from 40 Hz to 70Hz with resolution as good as 0.001 Hz. It have three channel voltage and three phase current independent output, any programmable setting, low phase shift, high stability 0.01%/1min, as standard three phase voltage source, three phase current source, three phase power source and harmonic source, is a high precision portable calibration tool in electrical laboratory. It can set 3P4W, 3P3W, 1P3W, 1P2W type, forward and reverse outputs, active power and reactive power output.

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 ~ 63 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output
  • Voltage, current output a wide range, big power, high stability, waveform distortion degree is small
  • Strong with load ability, but it can take capacitive, sensibility, resistance of composite type load or load and load regulation is higher than 0.01%
  • To apply the 32 bit MPU + DSP + CPLD, powerful flexible
  • To use hardware PID, fast response, the change of load will not cause output volatility
  • Industrial frequency waves as high as 5000 points a week of the wave kneading, signal output without filter, precise output waveform, the harmonic output precision, harmonic distortion degree is small
  • Range switching automatically
  • To use software calibration, simple operation, stable and reliable
  • Display of vector diagram, adjustable to IEC387 OR DIN410
  • Big touch screen, 7-inch TFT color LCD display, English interface, operating simply
  • To have perfect over-current, over-voltage, heat, a shorts-and-opens, overload protection, failure detection automatically
  • With RS232 interface, and PC connection
  • To take place machine software, it can be output through the PC software program
