The Schneider Electric Varlogic RT12 is a 12-step automatic power factor controller designed for intelligent capacitor bank management in low-voltage 3-phase electrical systems.

Engineered for industrial and commercial power factor correction panels, the RT12 continuously monitors system voltage and current (via external CT) and automatically switches capacitor stages to maintain the preset target power factor.

Operating within a wide voltage range of 320–460 VAC, this controller ensures reliable compensation performance in fluctuating network conditions, reducing reactive power penalties and improving overall energy efficiency.
