The Rectangular Regulator is a high-performance voltage regulator rectifier designed specifically for Kohler engines. It efficiently regulates voltage to maintain a stable electrical output, while converting AC to DC to keep the engine's electrical system functioning smoothly. Featuring over-voltage protection (OVP), this regulator safeguards the engine’s electrical components from damaging voltage spikes. With its full-wave design, the Rectangular Regulator offers reliable and efficient performance, serving as a direct replacement for several older models.
