It 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.
Type:
GF303H program-controlled three-phase standard power source (industrial control model)
Main functions and features
1. To set up and take the load regulation of voltage, current, phase angle , frequency and power factor etc;
2. To set 2 ~ 128 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output;
3. Frequency points is adjustable (AB and phase C);
4. Voltage, current output a wide range, big power, high stability, waveform distortion degree is small;
5. 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%;
6. To apply the 32 bit MPU + DSP + FPGA, powerful flexible;
7.To use hardware PID, fast response, the change of load will not cause output volatility;
8. 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;
10. To use software calibration, simple operation, stable and reliable;
11.To have big screen, 320 x 240 LCD display, Chinese or English interface, operating simplely;
12. To have perfect over-current, over-voltage, heat, a shorts-and-opens, overload protection, failure detection automatically;
13. With RS232 interface, and PC connection
14. To take place machine software, it can be output through the PC software program;
