This power supply can provide 10 A currents. Its regulation is made by 7812 integrated circuit. The power transistors must be equipped with excellent heatsinks. The resistors are wire with at least 10 W output The circuit is from the book Mechatronics Sourcebook of Newton C. Braga, published in the United States. The TIP31 transistor must also be mounted on a heat radiator, as should the integrated circuit. The transformer secondary is 10 A.
