FEATURES
- 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.
- 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 value 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 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.
