Product Description

The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.

Our APF equipment is module structure,there are two types Wall Mounted and cabient mounted.The Wall Mounted type is preferred to be used in equipment improvement which is very convenient to install.
 

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
