Features
1. 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
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 value 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
9. Range switching automatically
10. To use software calibrationon, simple operation, stable and reliable
11. To have big screen, 320 x 240 LCD display, Chinese or 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 software, it can be output through the PC software program
