Schneider Electric 5850-RC12V120 Programmable Logic Controller

Schneider Electric 5850-RC12V120 VarLogic RC12 is a SCR‑based reactive power controller designed to regulate VAR in 120 VAC electrical networks, delivering 12 discrete firing steps across a 50/60 Hz supply with a maximum switching current of 5 A and a nominal control load of 7 VA. This 12‑step RC12V120 variant sits in the VarLogic RC12 family and is intended to modulate reactive power to support voltage stability and improve power factor when coordinated with capacitor banks or reactors in industrial or commercial distribution systems. The unit weighs about 1.0 lb and, according to marketplace listings, is discontinued by the manufacturer, reflecting its status as legacy Schneider Electric hardware.
