The CoEpo-APF series active power filter is connected in parallel to the power system. Through external sampling circuits, it collects real-time power system data. The device's internal core computing chip analyzes the harmonic component data in the system and controls the high-frequency switching of IGBT to output a current that is equal in magnitude and opposite in direction to the harmonic current in the system, thereby canceling out the harmonic current in the system to achieve the goal of managing harmonic currents.

Product Features
1. Capable of harmonic management, reactive power compensation, and three-phase unbalance management. The priority of functions can be flexibly adjusted according to on-site requirements.
2. Full response time of 10ms, enabling the system to maintain an ideal state with THDI less than 5%, PF reaching 0.99, and three-phase unbalance less than or equal to 3%.
3. Can filter 2nd to 50th order harmonics. Within this range, harmonic orders can be arbitrarily selected, and the filtering output can be adjusted to achieve the desired filtering effect.
4. Reactive power compensation range (-1 ~ 1), capable of switching between capacitive and inductive reactive power to meet the compensation needs of equipment with rapidly changing reactive power, such as stamping and welding machines.
5. Modular design for easy maintenance and installation. Supports both rack-mounted and wall-mounted installation methods.
6. Independent air duct design ensures excellent heat dissipation capability. Equipped with a comprehensive temperature detection system to monitor device temperature in real time.
7. Comprehensive protection functions with 16 types of protection to ensure device and system safety.
