Low-voltage active power filter APF Technical Features: 1, the main circuit PWM control converter, constitute a parallel active power filter; dual closed-loop control circuit tracking control technology, the use of high-speed large-capacity computer chip DSP, real-time, fast detects the load current harmonic components and reactive components, accurate current output compensation, filtering efficiency of greater than 90%, the response time of less than 10ms. 2, according to user load characteristics, optionally set the following three ways: a single filtered load harmonic current; single stepless compensation load reactive power, realize inductive, capacitive reactive bi?? compensation, so that the power factor is always 1. ? Filtered load harmonic current and reactive power compensation system. 3, by the system grid impedance change is small, low voltage Harmonic filter to eliminate possible with the grid impedance parallel resonance occurs, to overcome the traditional shortcomings of LC passive filter. 4, a single device can be active power filter APF 2 times to 50 times for a broad spectrum of harmonic compensation, to overcome the traditional shortcomings of LC passive filter needs more single-tuned filter branch of the group. 5, the filtering effect is not affected by changes in grid frequency, to overcome the traditional LC filter frequency offset sensitive defects. 6, the harmonic current compensation object beyond the rated output current of the power active filter device Foshan harmonic control, will not overload the power active filtering devices to ensure safe operation of equipment in real time. 7, the use of large-screen, high-definition, Chinese menu display color touch screen interface. Real-time display of voltage, current, harmonics, power factor and other electrical parameters of the system, real-time display device operating parameters and historical events records, and can be 485 to communicate with the host computer. 8, a plurality of active power filter APF device can be used in parallel. 9, with the TSC dynamic reactive power compensation device in combination with harmonic control, increasing the reactive power compensation capacity and compensation accuracy; with TSF passive filter used in combination to increase the capacity of harmonic filter and filter precision . Active power filter input voltage range rated voltage of 380V Germany harmonic control, can withstand -40% to + 20% voltage fluctuation, frequency of 50 / 60Hz, can withstand +/- 5% of the frequency fluctuations, to adapt to each different conditions of power quality environment. Meanwhile, if the voltage fluctuation exceeds the upper limit, the machine automatically latching output, and an alarm. Automatic current limiting automatic limited within the range of the rated output capacity of 100%, if the load side harmonic currents greater than the rated capacity of the machine, the machine will continue to output harmonic current compensation within the rated capacity, it will not lead to overload itself overloaded or out of service. Load short-circuit protection can withstand the impact of short-circuit load instantly, eliminate restarted after a short circuit. led lights Harmonic Shilong District _ _ Xi Connaught Electrical and Mechanical Pingdingshan City, Henan conventional harmonic suppression provided by Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
