Power Factor Correction

LCD Display

Vision UPS active power filter

The user friendly LCD display offers access to all parameters, waveforms, harmonic spectrum system power quality, settings, status and alarms, events log and multi-language.

Close/Open Loop Control

The CT is allowed to install at source or load side for measure the harmonic current from the load. When CT is installed at source side, the close loop control method is used for best accuracy of harmonic current compensation. (When CT is installed at the load side, the open loop control will be used).

Harmonic Current Generator

The Vision APF behaves like a harmonics current generator. It will measure the harmonic generated from the non-linear loads and cancel these harmonics with a newly generated, opposite phase shifted harmonics current of the same amplitude.
