Features:
1.To set up and take the load regulation of voltage, current, phase angle, frequency and power factor etc, can be used as a large current source, voltage source and power source.
2.Seting 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.Apply the 32 bit MPU + DSP + CPLD, powerful ?exible.
6.Using 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 ?lter, precise output waveform, the harmonic output precision, harmonic distortion degree is small.
8.Range switching automatically.
9.Using software calibration, simple operation, stable and reliable.
10.Vector diagram display, adjustable to IEC387 OR DIN410.
