600V/690V 50/60Hz active power filter
Introduction of Functions
Harmonic Filter
Dynamic reactive power compensation
Correct unbalanced 3 phases:
Special Features
Higher efficiency, lower loss
Patented technology of ripple cancellation and stagger converter is characterized by high current tracing speed, small ripple and low loss;
Multi-DSP collaborative control can guarantee highly accurate control and high-speed computation;
The harmonic filter rate is high. Toward target harmonics, effective harmonic filter rate can reach 97%;
It can filter up to over 20 kinds of harmonics at the same time, and harmonics in side of the 50th at most
Low-loss ceramic alloy;
Magnetic Core reactor is characterized by low noise and high efficiency.
More functions, more modes
Fractional compensation of harmonics can be set according to actual needs;
Harmonic reactive compensation is equipped with 4 working modes, namely, “filter priority”, “reactive power priority”, “harmonic filter only”, “reactive power compensation only”, which can satisfy the compensation need for various power distribution systems;
Balance compensation function can balance the load current among phases;
RS485 interface, standard MODBUS RTU communication protocol, and computer remote monitoring function.
More stable, more reliable
Higher power density, easier installation and maintenance
