400V/300A Active Harmonic Filter

400V/300A Active Harmonic Filter
Product Detailed
Advanced modular design; Three-level topology; Compensate harmonic, reactive power, unbalanced load; Filtering efficiency>97%

Active Harmonic Filter 300A

High efficiency

Three level topology, reduce power components consumption, efficiency can reach 97%.

THDi<5%Advanced software algorithms, can filter 2~50th harmonics at the same time.

Compensating times can be chosen, to make efficiency higher.

3DSP+CPLD all-digital controlling method, making calculation faster and more accurate.

Supply harmonics, reactive power and unbalanced load compensation modes, give users more choices.

Support instantaneous reactive arithmetic and FFT arithmetic, faster and more accurate.

Easy using

Modular design, each module weighs 16Kg~40Kg, make it very easy to be transported. The high density helps saving more space.

Can be installed in both rack/wall mounting type, give users more options.

Setting work is also easy, help users operate it conveniently.

We supply complete materials that can help customers choose AHF by themselves.

Friendly communication interface, shows all information including grid voltage/current, grid PF, grid frequency, load current, compensation current etc.

And we can provide with monitoring software, users can be aware of more information and set the system.


Chips, Semiconductors, Capacitors are from Germany, USA and Japan.

Can adapt to a range of -40%~20% voltage.

Complete self-protection functions make Sinexcel AHF more reliable.

Sinexcel AHF has an application time for more than 4 years in 30 industries, over 100,000A of total capacity.

Service Advantages

Modular design, complete parts and back-up machines, machines within the warranty period failed can be directly replaced with new ones.

Sense of responsibility and commitment to the customers.
