Power-factor correction

1309hvac02pThe kVAR StacoVAR mini is a wall-mountable, automatic power-factor correction bank. The product uses the same components as the StacoVAR mini to maintain the desired power-factor level through a microprocessor-based controller that adjusts to system load conditions. The company reports that facilities charged a penalty for poor power factor can benefit from more efficient use of supplied power and avoid penalties and surcharges. Models are available from 11 1/2 to 28 kvar at 208 V, 15 to 37 1/2 kvar at 240 V, and 28 to 75 kvar at 480 V.
