Functions and Features
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;
To set 2 ~ 31 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output;
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 + CPLD, powerful flexible;
To use hardware PID, fast response, the change of load will not cause output volatility;
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;
Range switching automatically
To use software calibration, simple operation, stable and reliable;
Display of vector diagram, adjustable to IEC387 OR DIN410;
Big touch screen, 7-inch TFT color LCD display, English interface, operating simply;
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;
