Harmonic output

The three-phase program-controlled precision test power supply can accurately output the 2nd to 22nd harmonics, and each harmonic can be arbitrarily combined and output at the same time.

 

 The load capacity will be reduced by half when outputting harmonics. In order to ensure reliable and accurate harmonic output, please ensure that the load does not exceed half of the rated value. Especially the voltage output, because the voltage output is often used as the power source of the device under test, the power consumption on it will be greater.

Product Features

1. The three-phase program-controlled precision test power supply can output a pure sinusoidal power signal with a distortion of 0.1% (typical value).

2. The harmonic output can be superimposed on the fundamental wave.

3. The frequency output is arbitrarily adjustable from 40Hz to 65Hz, with a resolution of 0.005Hz and an accuracy of 0.005Hz.

4. Phases A and B are a frequency reference, and phase C is a separate frequency reference, so it can be divided into phases.

5. The phase can be adjusted arbitrarily from 0 to 360 degrees, which can easily simulate various power supply conditions and even reverse power transmission.

6. Strong loading capacity, can carry capacitive, inductive, resistive load or composite type load, and the load adjustment rate is better than 0.03% RG.

7. Excellent temperature stability, the core device is a military grade product with a temperature coefficient as small as 1PPM, which can
    ensure the accuracy of the output in the outdoor temperature environment.

8. Using 32-bit MCU + DSP processor, powerful and flexible.

9. The waveform of the power frequency weekly wave is up to 50000 points, and the internal signal output does not require a filter forsmooth filtering,which
     ensures the accurate output of the waveform, allows the system to output accurate harmonics, and also makes the system have excellent harmonic distortion index.

10. It can be easily connected to PC through an RS232 to expand other functions.

11. Perfect overcurrent, overvoltage, overheat, short circuit, open circuit, overload protection.

12. The hardware PID has extremely fast response, and the load change will not cause the slightest fluctuation of the output.

13. 320 * 240 LCD display, Chinese interface, simple operation.

14. Open the communication protocol to facilitate secondary development (RTU / FTU / electricity management terminal / public
     transformer metering terminal factory automatic verification).

15. Three-phase program-controlled precision test power supply can carry pure capacitive load.

16. Combined with PC software, the energy meter can be checked.
