200A Dynamic Harmonic Treatment Free Parallel Connection Filter Bank

  Dynamically compensate 2-50 times all harmonics or specific harmonics Reduce harmonic to less than 5%     What Is Harmonic?   A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency,.   i.e. if the fundamental frequency is 50Hz, the frequencies of the next harmonics are: 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 100 Hz (4th harmonic) etc.         Main nonlinear load includes: UPS Switching power supply Rectifier Frequency inverter Frequency adjustable air conditioner Inductive heating furnace Electronic computer Charger Main harmonics polluting industries:        Product Description   Product Function: filter bank is a new electronic harmonic filtering device to reduce voltage harmonic and current harominic and improve power quality.   Based on voltage source inverter, it’s connected in parallel with non-linear loads which need to compensate.   For compensating harmonic current which is with changing Amp and frequency and reactive power, it overcomes the shortcomings of traditional passive filter. It has the advantages of high compensation accuracy and fast dynamic response etc.   APF adopts innovative intelligent control algorithm, through space vector modulation technology, generates compensation current with equal value and opposite direction to harmonics and reactive power and puts it into electric network and achieves harmonic suppression and reactive power dynamic compensation.     150A multilevel active harmonic filter Main Technical Parameters     400V APF 480V APF 690V APF Rated input AC line voltage 380V 480V 690V Input voltage range -40% ~ 20% -20% ~ 20% -30% ~ 15% Electric network 3 ph 3 line, 3 phase 4 line 3 ph 3 line 3 ph 3 line Rated current 25A/35A/50A/60A/100A Free parallel connection 75A/150A/225A/300A 75A/150A/225A/300A CT 150/5-10,000/5 Power quality improvement function 2-50 harmonics selectable, adjustable Reactive compensation Unbalance compensation Fast response time <50μs <100μs Full response time <15ms <20ms Filter ability THDi<5% Target power factor -1 to 1 adjustable Communication interface RS485, internet interface Communication protocol Modbus, TCP/IP Protections Over voltage, under voltage, short circuit protection, inverter bridge reverse protection, over compensation protection Installation Wall type/rack type Cabinet Cabinet Elevation <1500m, power rating reduced at 1500-4000m Ambient temperature -10°C- 40°C Relative humidity 5%-95%, without condensation     Comparison with Europe active filter   Brand Beijing Green Power Europe brand Product Picture Input AC Voltage 380V/480V/690V 400V/480V Input AC Range(V) 380V -40%~ 20%/ 480V -20%~ 20%/ 690V -30%~ 15% 400±10%/ 480±10% Input Frequency (Hz) 50/60HZ /-5% 47Hz-63Hz Dimension of 50A (mm) 440*190*590 360*590*290 Module Quantity  for Parallel not Limited Max 5 N.W.(Kg) 35 47 Installation Way Rack/Wall-mounted Cabinet Noise(dB) 56dB 60dB Cooling Intelligent Air Cooling Forced Air  with Inner Liquid Filtering Range 2~50 harmonic and it can be filtered at the same time 2-50 harmonic Appointed Time Harmonic Filter Yes 2~50 harmonic optional,and LCD and software monitor no Switch Frequency Average 20KHz 16KHz Control FFT & Instant Reactive Power FFT Topology 3-leve Inversion 2-level Inversion Efficiency >95%,THDi<5% THDi<5% Response Time Fast Response Time≤50us, Full Response Time≤5ms 300us Reactive Power (VAR) Compensation Yes.Efficiency ≥99% Yes 3 Phase Balace Compensation Yes Yes Overload Protection Yes,Auto Current Limit at 100% Rated Output 250% for 10ms HMI LCD No Protocol/Interface Ethernet,RS485,Modbus Protocol, TCP/IP Interface,Dry Contact RS485, Ethernet, TCP/IP Interface PC Software Yes,All Data With Setting Interaction Yes, AHF Viewer   Summary: Beijing Green Power active filter general performance is better than Europe brand. The items with red color is better performance.   Active harmonic filter other features Have user-friendly operating software for easy operation. Could withstand load short circuit shock, and restart after removal of short circuit. Automatically eliminate resonance, not affected by electric network impedance and system impedance change. Could simultaneously filter 2-50 harmonics in three-phase four -line distribution system, and is able to choose compensation or not for each harmonic from 2-50 harmonics . The system has fast and complete fault self detection features, including undervoltage or overvoltage , overcurrent, fan failure , power devices over temperature , input fuse failure etc. fault self detection, all fault could be alarmed by APF and automatically taken corresponding actions. APF’s high-frequency carrier itself can not be feedback to electric network. Overcompensation must be avoided during filtering, i.e. APF could realize only filtering without generating reactive power to avoid over compensation completely, or by setting target power factor, the remaining energy after filtering is used for reactive power compensation. Have soft start control loop to avoid too large inrush current while starting and to limit the current within rated range. When the system is powered down, the filter could be automatically disconnected; After system recovery, the filter can be automatically restored.   Selling Points Selling Points   CE Certification   FAQ 1) Is there a warranty?
