AFE

Performance characteristics:

1. Using PWM technology, four quadrant operation, accurate output phase and effective suppression of high-order harmonics;

2. Adopted DSP2812 processor, with high speed, high precision, good stability and strong anti-interference ability;

3. The voltage distortion rate is less than 5%, which meets the requirements of IEC61000-3-2 and GB / t14549;

4. Improve the braking effect to meet the engineering requirements of fast braking and frequent braking;

5. It can be used in parallel for high power applications;

6. Equipped with touch screen, it can display AC current, voltage, power and fault information;

7. It has the functions of overvoltage, undervoltage, short circuit, overheating, overload, etc;

8. Feedback: using self diagnosis technology to ensure the accuracy of the output voltage, prevent the current return, so that the inverter will not be affected;

9. Energy saving: the regenerative energy is fed back to the state grid, the efficiency is as high as 97%, increase the operation economic benefit, and the energy saving and environmental protection are realized;

10. Substitutability: brake unit + resistor = energy feedback brake, completely replaced;

11. Safety: advanced power electronic technology and high performance IGBT are used as switching devices;

12. Practicability: the system has good power saving effect, low calorific value, high safety and small maintenance workload;
