Part of PowerLogic
AccuSine PFV+ addresses power quality issues by simple, effective elimination of leading or lagging power factor and reduction of voltage fluctuations. Its unique design helps enhance equipment operating life and improves system power performance, and offers multiple features in one complete package. Power Factor correction with AccuSine PFV+ is worry-free and with no risk of resonance.
Is dirty power stealing from you? To help you mitigate against power quality issues, AccuSine PVF+ provides reliable and comprehensive electronic VAR injection for very precise displacement power factor correction and mains current balancing.

What is power quality?
In an ideal three phase power system, voltages are at nominal magnitude and frequency, perfectly balanced and with a perfect sinusoidal waveform. Any disturbance on one parameter (magnitude, frequency, waveform, or symmetry) is classified as a power quality issue. There are a variety of power quality disturbances – voltage dips, harmonics, transients, etc. – all of which can have negative impacts on the electrical system and equipment, such as power outage, device damage, failure, overheating, degraded performance and reduced equipment life.
AccuSine PFV+ stops power quality issues like voltage sags and flicker due to load current fluctuations (VAR compensation). For larger power quality applications, AccuSine PFV+ can be combined with a capacitor bank to reduce system cost. It can add or subtract to the capacitor bank output, achieving high speed reactive compensation with infinite resolution. It also provides high speed Powoer Factor correction where traditional capacitor banks are unable to track loads.
