Schneider Electric Varlogic RT 6-Step Power Factor Controller – 320–460V AC

The Schneider Electric Varlogic RT (Reference 51207) is a microprocessor-based Power Factor (PF) Controller designed for automatic regulation of capacitor banks in low-voltage power factor correction systems. With 6 control steps, this controller ensures efficient reactive power compensation and maintains optimal power factor levels in industrial and commercial installations.

Operating within a voltage range of 320–460V AC, the Varlogic RT continuously measures system parameters and automatically switches capacitor stages ON or OFF to achieve the desired power factor. Its intelligent control algorithm enhances capacitor lifespan by optimizing switching sequences and reducing unnecessary operations.
