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 production of the enterprise and so on.
Main Functions and Features
To set up and take the load regulation of voltage, current, phase and frequency of the power factor;
To be set to 2 ~ 128 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 very small;
To have strong with load ability, and 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 the 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, automatic failure detection;
With RS232 interface, and PC connection;
To take place machine software, it can be output through the PC software of program.
