24V To 12V Converter | Circuit Diagram Many times we have the requirements of 24V to 12V converter. The circuits shown below can be used to convert 24V DC to 12V DC. These type of circuits are also called DC to DC converters can step down 24V DC to 12V with the help of voltage regulators ICs. 24v to 12v converter – Circuit Wiring Diagrams As shown, the 24v to 12v converter circuit is nothing more than an integrated adjustable voltage regulator that acts on a group of power transistors in parallele transistors can be said to perform heavy duty while the regulator responsible for controlling them. Where 24 v input connector of the battery. 12V connector is the output and Gnd connector must be grounded.
