MASTER Series Active Power Filter is a truly effective solution to improve the harmonic pollution, which adopts the most advanced active harmonic dynamic compensation technology to eliminate harmonics. MASTER Series Active Power Filter can monitor non-linear load current waveform in real time, and separate harmonic current. The IGBT inverter circuit of MASTER can output equivalent harmonic current to offset the load harmonics and ensure that the current from the grid is sinusoidal, achieve harmonic filtering function.

In addition, MASTER can provide leading or lagging reactive current to improve the grid power factor, and then realize dynamic reactive power compensation.

Main features:

- Dynamic active filtering function can improve the power quality comprehensively.

- DSP digital control technology with 20kHz switching frequency, can ensure quick response to the dynamic changes of the load.

- The number of harmonic compensation is selectable from the maximum times of 50.

- The optional reactive power compensation at the same time.

- Phase imbalance compensation.

- Automatic current limiting function to avoid overload.

- High efficiency, less than 2.5% full load loss rate.

- Parallel installation, easy installation, small size.

- Realizes maximum energy saving through reducing line loss and eliminating transformer and motor heat.

- Filtering effectiveness not influenced by the changes of impedance from the system, and automatic inhibition of the system resonant.

- Partial compensation, part of compensation or total compensation are selectable according to the power distribution structure. Current Transformer (CT) can be located at either the Power supply side or load side.
