APF Active Power Filter Cabinet

Why does your factory urgently need dynamic management?

With the widespread use of non-linear loads such as frequency converters and rectification equipment, the harmonic pollution of the power grid has become increasingly severe. This not only causes transformers to overheat and accelerates the aging of cables, but may also lead to capacitor explosions, relay protection malfunctions and other serious accidents. The more direct economic losses come from the "harmonic fines" imposed by the power supply department. Traditional passive filters can only target specific frequencies and are prone to resonance with system impedance, causing secondary pollution. Our APF Active Power Filter Cabinet adopts advanced dynamic management technology. It is like a "purifier" for the power grid, capable of real-time monitoring of current waveforms, automatically identifying and generating compensating currents of equal amplitude and opposite direction to the harmonic amplitudes. This "using poison to counter poison" approach can completely eliminate the impact of harmonics, control the total harmonic distortion rate within the national standard range, and allow you to completely say goodbye to fines and the risk of equipment burning out.

Core advantage

The core value of this APF Active Power Filter Cabinet lies in its high dynamic response capability and high-precision control effect. Firstly, it has a full-range harmonic control capability, capable of filtering out more than 95% of harmonics, including common 5th and 7th harmonics, as well as higher-order harmonics ranging from 2nd to 50th. Secondly, it significantly improves power quality by controlling harmonics, reducing line losses, and increasing the effective load rate of transformers, which is equivalent to an expansion of the transformer capacity. More importantly, it can effectively protect sensitive downstream equipment, extending the service life of motors and frequency converters. For many factories, the electricity savings and penalty avoidance achieved in the first month after installing this equipment often cover a considerable portion of the equipment cost, resulting in an extremely high return on investment.

Junray Electrical's Commitment

As a seasoned manufacturer with international certifications such as ISO, CE, and CCC, Junray Electrical is well aware of the harshness of industrial environments. This APF Active Power Filter Cabinet adopts a floor-standing design and has a protection level of IP4X, suitable for various distribution room environments. The interior uses high-quality APF active filter modules, combined with standardized power and weak current separation wiring techniques, ensuring the electromagnetic compatibility and stability of the system. The equipment features powerful intelligent detection capabilities, which can automatically adapt to load changes without frequent manual adjustments. At the same time, we have built-in multiple protection mechanisms such as overvoltage, undervoltage, overcurrent, and overtemperature protection. In case of system abnormalities, it will automatically shut down and give an alarm. The dedicated cooling and ventilation design ensures that the modules remain calm and stable even during long periods of high-load operation.

Widely applicable scenarios

Our APF Active Power Filter Cabinet is widely used in places with extremely high requirements for power quality. It is indispensable as a "power grid guardian" in manufacturing plants with a large number of frequency converters, chemical plants equipped with rectification equipment, and data centers with high data density. For large infrastructure projects, it can also effectively manage the harmonic interference generated by construction equipment. Choosing Junray Electrical means choosing a partner who understands technology and values quality. We provide a full-process service from selection, installation to after-sales, ensuring that your power distribution system reaches the optimal state.
