Schneider Electric VarPlus Logic VPL12N Power Factor Controller – 12 Step, 90–550V AC

The Schneider Electric VarPlus Logic VPL12N is a microprocessor-based Automatic Power Factor (PF) Controller designed for advanced control of capacitor banks in low-voltage power factor correction (PFC) systems. With 12 output steps, the VPL12N provides precise reactive power compensation, ensuring optimal power factor levels and reducing energy penalties imposed by utility providers.

The controller continuously monitors system voltage and current (True RMS measurement) and automatically switches capacitor stages ON or OFF to maintain the programmed target power factor. Its intelligent control algorithm optimizes capacitor usage, balances step switching, and enhances overall system efficiency.
