Sinopak Active Power Filter - China

Sinopak 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.
