Power Supply 12V 5A With the 2N3055 can provide stable output voltage of 12 volts and a maximum current of 5 amperes. 5A adapter 12 volt circuit, with a current amplifier transistor 2N3055 can be purchased in kit form or assembled themselves with the PCB in the market. PCB for 12 V 5A power supply can be found by 2N3055 PCB Ronica and Saturn brands,price 12V 5A power supply circuit in the form of a ready-made kit is not too expensive. A complete range of power supply and list of components to assemble their own 12V 5A can be seen in the following figure.
12V 5A Power Supply With 2N3055
12V 5A power supply circuit with 2N3055 transistor current amplifier can be made easily without the need for additional settings and components needed readily available. 12 5A power supply circuit above consists of the following parts.
Part of the voltage regulator, serves to provide 12 volt power supply output is stable. component that functions as a regulator in the circuit above is IC LM7812.
Current amplifier is used to bypass the regulator output current fixed voltage power supply with 12 volts which is controlled by IC LM7812. Component of the current amplifier using a power transistor type 2N3055.
12V 5A power supply circuit above is not equipped with rectifier part because of a series of power supply 12 volt power supply is intended for front amplifier, tone control, VU displays amplifier and tuner in the assembly or portable tape where the DC voltage source to 12V 5A power supply circuit can be drawn from the power supply output terminal of the power amplifier is used.
