Product Description

  Introduction 
 LVAF active power filter is a new power electronic device of dynamically suppressing harmonics, reactive power compensation, through real-time detection of the load current waveform and DSP calculation, to obtain content of load current harmonic, then a PWM signal to inverter controlled by IGBT, such, to produce a current as big as load harmonic current but opposite direction into power supply system. Finally, the harmonic is filtered

Application
It is suitable for any non-linear loads like:
softstarter
UPS,Inverter,EV charger etc
Lift,welding machine,control motor
Electronics data handle,IDC
Lights


Main Parameter
