Features:
● Use DSP+CPLD all digital control core, three-level topology technology, advanced harmonic detection algorithm and PWM control strategy to achieve accurate compensation of harmonic current.
● Adopt modular design, which facilitates parallel connection of multiple modules, takes up little space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses ensures the stable operation of the equipment.
● It can filter harmonics in a wide range of harmonics, from 2 to 50 harmonics, and solve the problem of three-phase unbalance at the same time.
● The harmonic filtering rate is high. If the capacity allows, the harmonic current filtering rate can be as high as 95%. Set 100% current limiting output to ensure long-term stable operation of the equipment.
