High Current Power Supply IC7812
High current power supply IC7812 can provide output with a large current capacity when added to the current amplifier circuit as shown in FIG power supply circuit current below the 7812 high. High current power supply IC7812 on the circuit below can provide a stable output voltage to 12 volts DC and a maximum current that can be streamed 35A. A good power supply circuit is a power supply that can provide a stable output voltage even if the load gets changed, the power supply circuit in the circuit below the expected results so as to output voltage remains at the level of 12 volts. Circuit of high current power supply IC7812 is composed of several parts as shown in the following circuit schematic.
Circuit Of High Current Power Supply IC7812
Above power supply circuit is a series power supply with a fixed output voltage. Still used as a voltage regulator IC LM7812 regulator to be able to provide power supply output voltage remains at 12 volts DC voltage level.
Components Of The High Current Power Supply IC7812
