Save money and energy with power factor correction

Power Factor Correction is the use of technology to restore power factor as close to unity as possible.  This is usually achieved by the additional use of capacitors to the electrical network. The Enerdoor FINSVG provides a better solution for power factor correction than the commonly used capacitor banks. Unlike capacitor banks, it is immune to harmonics through active load balancing by advanced digital control. The compensation capacity never declines and the system is capable of compensating both inductive and capacitive reactive power. 

The Enerdoor FINSVG offers compensation starting at 30 KVAR with a modular design and can be either wall or rack mounted. It is available starting at 208 Vac and may be installed in either a single unit system or multiple, parallel modules for entire facilities.
