400V 50-600A Active Harmonic 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 microcrystal 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

l  Optical fiber drive can guarantee high security, reliability and anti-jamming capability;

l  Multi-protection, strict thermal design can ensure the secure and reliable operation of the system;

l  Advanced control algorithms can offer stable operation for various complex environments, and it can also conduct parallel operation with capacitor compensating box;

l  Digital control, LCD working platform Chinese or English;

l  Self-diagnosis function

l  Record of historical events function

Higher power density, easier installation and maintenance

l  Modular design of converter can guarantee high power density, and easy installation and maintenance;

l  Output capacity is high. Single-unit output capacity can reach up to 600A;

l  It can conduct multi-machine parallel operation to satisfy various needs for compensation capacity.

l  Automatic current limiting will be conducted once output capacity is fully loaded, so it is free of the trouble in overloading;

l  Detection methods of source current and load current are optional for the convenience of field installation.
