Apfm Series Active Power Filter Module

APFMSeries Active Power Filter ModluleRated Voltage: 0.4kvRated Frequency: 50HZ Function:Sanhe power APFM series active filter module detect load current through the current transformer,then calculate by the means of the internal DSP, extract the harmonic components of load current, and send PWM signal to the internal IGBT, control inverter to produce a load harmonic current equal in size, in the opposite direction of harmonic current injected into the power grid, to achieve the purpose of filtering.Application: widely used in industrial and commercial power users.Installation: indoorProduct featureCompact and reasonable structure, flexible installationAdvanced control algorithm, software reliabilityDSP+FPGA control system adopts vector screening technologyDynamic filtering of 2 ~ 51 harmonics, but also selective filtering of specified harmonicsHarmonic compensation, reactive power compensation and three-phase unbalance compensationA variety of capacity modules, any capacity combination parallel, good expansion performance, to meet the needs of different capacity systemUse standard communication port and protocolFault alarm and record function, up to 500 alarm recordsComplete and effective protection measures, such as over voltage protection, under voltage protection, short circuit protection, inverter bridge reverse protection, over compensation protectionIn the process of load change, if there is resonance,APFM will self-judge and exit the system, and alarm at the same time to avoid faultTechnology SpecificationRated voltage208V-800VPower net frequency50Hz0Hz±5%Rated current50A/100A/150AElectrical wiring3-phase 3-wire-phase 4-wire systemEfficiency≥97.5%Filter capacityTHDi
