Program-Controlled Three Phase Standard Power Source GF303 GFuve

Back

GF303 Program-controlled three phase AC standard power source is a high precision three phase AC standard current source and AC standard voltage source.

Description

GF303 Program-controlled three phase AC standard power source is a high precision three phase AC standard current source and AC standard voltage source. According to DL/T 2213.1-2021 AC standard power source Part 1:General requirements. It is suitable for power department, metrology department, quality control department, research units, institutions of higher learning, electric energy meter, power distribution terminals, power supply management, load control, power quality, reactive power compensation device and the production of enterprise etc.

FEATURES

  • To set up and take the load regulation of voltage, current, phase angle, frequency and power factor, also can be used as AC current source, AC voltage source or power source.
  • To set 2-128 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output.
  • Frequency value is adjustable (AB and phase C).
  • 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 + FPGA, powerful flexible.
  • To use hardware PID, fast response, the change of load will not cause output volatility.
  • Industrial frequency waves as high as 50000 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.
  • To have big screen, 320 x 240 LCD display, Chinese or 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.
