Features

Program-controlled three phase standard power source-Power Source-GFUVE Electronics

  • 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.
