Page 11 AcFee Active Power Filter  Working Principle Picture1 APF Working Principle Chart 1. Working Principle User can set parameters so that the device can simultaneously have the function of filtering harmonics, dynamic reactive power compensation, and three-phase unbalance compensation. The principle of filtering harmonic is that APF collects the current signal in real time through current transformer, separates the harmonic part through the internal detection circuit,...
Page 12 AcFee Active Power Filter automatically limit the output to 100% of the rated capacity, no overload will happen. The principle of three-phase unbalance compensation is that APF collects system current signals in real time through external current transformers and sends them to DSP for real-time calculation to judge where the system current is in an unbalanced state, and at the same time calculates the current difference of each phase when it reaches a balanced state.

DC capacitor acts as an energy storage device, and supplies energy by outputting compensation current through IGBT and internal reactor. DC capacitor acts as an energy storage device, and supplies energy by outputting compensation current through IGBT and internal reactor.

Due to the air duct isolation, there is no need to install a dust filter in general environment, but for hash environment, such as high temperature, high humility, and a lot of conductive dust environment, please contact our product engineers when making on-site application solutions, and confirm the specific heat dissipation scheme.
Page 18 AcFee Active Power Filter temperature.  Device Handling  Since the weight of a single APF module is 30kg-55kg, it is recommended to be transported by two people within a short Attention! distance, if transported over a long distance, it needs to be completed with the help of transportation device.

Page 23: Optional Accessories Installation
AcFee Active Power Filter  Optional accessories installation 1. External Sampling CT The APF is installed in parallel in the system, and the current transformer CT can be optionally connected to the grid side or load side on the touch screen, default is load side for installation.
Page 24 AcFee Active Power Filter In Figure6, if there are several modules in a cabinet, the total output current sampling CT2 is required in the cabinet to realize the sampling on the grid side. For the wiring when APF and capacitor are used together, the principle is that the main incoming line point of APF is closer to the load than the capacitor.
Page 25 AcFee Active Power Filter  Make sure that the current transformer is in a short circuit status until the CT connect terminals of the APF are connected.  Short-circuit the current transformer with the separable short-circuit terminal before separating the current transformer and APF.
