12v And 5v Dual Power Supply Circuit Diagram

We have simulated the circuit in proteus before building it on hardware.

12v and 5v dual power supply circuit diagram. Hi friend hope you are very well. Read detail more in a. You can select voltage levels are 3v 5v 6v 9v 12 15v at 1a and 3v 5v 6v 9v 12v 15v at 1a. Dual power supply circuit 12v and 12v.

Converting 220v ac into 12v ac using step down transformer. Digital dc regulator if you are looking for 5v dc power supply for the digital. Generating low voltage dc from the 220v or 110v ac mains is very useful and necessary in the field of electronics. The voltage ranges 5v and 12v are widely used in all kinds of simple electronic circuits so its meaningful to learn this simple construction.

Many ideas of 12v and 5v dual power supply circuit diagram at 3a max. Today i will show you how to create a dual power supply easily. Here we have used 1 amps step down transformer you can use up to your specifications and need. For such applications the above discussed design could be simply modified by using a 7812 ic and then subsequently a 7805 ic for getting the required 12v and 5v regulated power supply output together as indicated.

The centre tapped describes the voltage output of. A lot of 6v supply diagrams. The above given circuit illustrates a simple approach to construct a dual dc power supply of 5v and 12v from the 230v ac mains supply. Learn many ideas of 5v 12v dual power supply circuit diagram using 7805 7812 2n3055 and zener diode up to 3a output current.

Simple dc regulators 12v 15v 30v. Assemble the circuit on the pcb breadboard as per the circuit diagram shown above. The objective of this project is to convert 220v ac supply in to 12v and 12v dc supply that is why it is named dual power supply as we get positive. 5v power supplies digital power supplies.

Controls voltage output by s2 for vout and s3 for vout. And the both ic holds heat sink. Constructing dual power supply circuit. The converted 5v supply is available at pin 5 of u1.

This circuit has two leds to indicate output. 1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups. Testing dual 5v usb power supply circuit. We power most electronic circuits and devices by using 12 volt or 5 volt regulated dc supply hence we designed basic 12v and 5v dual power supply with easily available components and this circuit can used as general purpose regulator power supply source.

Now suppose you had circuit applications which needed a dual supply in the range of 12v fixed and also 5v fixed regulated supplies. The transformer is of 2a size. Low voltage dc like 5v 6v 9v 12v is used in electronics circuits led bulbs toys and many household electronics items generally batteries are used to power them but they need to be replaced time to time which is not cost effective and also takes our time energy. The primary terminals of the centre tapped transformer is connected with household supply 220v ac 50hz and output is taken from secondary terminals of the transformer.
