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 parallel. These 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. Of course, all the components (transistors and integrated) should be given with good heat dissipation and electrically insulated from the metal.
24v to 12v converter Adjustment :
Place the pot 10 k Ω at its maximum (fully open or 10 k Ω) and connect to the dc to dc converter output a lamp 12V / 50W. At the input connect the battery in series so the voltage is reached 24V. Place the output in parallel with the lamp tester a continuous scale with the right completion (around 50V). Begin to turn the potentiometer until the brightness of lights and tester showed 12V.
I am in need of voltage reducer 24v to 12v at least 40 amps for my truck and fortunately i found this site of yours to be very helpful. I can not afford to buy a voltage reducer coz i found it expensive. I want to build my own reducer if this site will allow me. but the problem is that i am not an electrician and i cannot make it.
Would you mind giving me the complete procedure, materials and the parts needed and specs to build one reducer for my truck?
Thank you and GOD bless.
