GF303D Portable three phase standard power source

Application

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.

Functions and Features

1. 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
2. To set 2 ~ 31 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output
3. Voltage, current output a wide range, big power, high stability, waveform distortion degree is small
4. 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%
5. To apply the 32 bit MPU + DSP + CPLD, powerful flexible
6. To use hardware PID, fast response, the change of load will not cause output volatility
7. 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
8. Range switching automatically.
9. To use software calibration, simple operation, stable and reliable
10. Display of vector diagram, adjustable to IEC387 OR DIN410
11. Big touch screen, 7-inch TFT color LCD display, English interface, operating simply
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
15. software, it can be output through the PC software program.Electrical parameters
