Sinopak Active Power Filter

Active Power filter
Active power filter (APF) is designed to filter the harmonics injected by non-linear loads in power networks. It can analyze the line current harmonics drawn by the loads and generate a compensation current dynamically at the opposite phase angle, thereby "neutralizing" the harmonic currents.Features 
1. Based on 3-Level topology circuit 
2. Modular design for a shorter delivery cycle and easy maintenance. 
3. Rack-mounted or wall-mounted design which can be easily combined and installed as needed. 
4. It is possible to compensate the 2nd~51st harmonics, or select a specific order of harmonics to compensate separately. 
5. Flexible compensation modes: 
Harmonic compensation,
Reactive power compensation, 
Three phase imbalance compensation 
6. Harmonic +Reactive power +Imbalance 
7. Remote communication interfaces, with real-time monitoring being achieved via PC machines.
8. A full automatic detection runs during the whole compensation process, and should it be restarted, self-diagnosis will function; then after the fault is removed, it will be automatically put into use. 
9. Free of harmonic resonance.
10.A user-friendly human-machine interface is configured to operate, and display system's real-time parameters like voltage/current waveforms, active power, reactive power, apparent power, power factor, harmonics, etc. 
11. Intelligent control circuit with perfect protection functions (against overvoltage, under voltage, over-heating, over current, etc.)Technical Specifications
