Main functions and features

To set up and take the load regulation of voltage, current, phase angle ,frequency and power factor etc;

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 points 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 simplely;

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;
