6 12 Volt Adjustable Power Supply Circuit

Power Supply has an adjustable output with a range of 6-12 VDC. The part that serves as a power regulator is Q1 TIP31. Then the controller output voltage is a voltage divider composed of R3, R4, VR1 and R2 provide bias to the base of Q2 to Q1 mengentrol power regulator. In a series of power supply is mounted 5.1 V zener diode which serves to make the minimum limit the output voltage with Q2.

Power Supply With transistor circuit is quite simple and can be made with the PCB holes, so for those who want to try to directly mempraktikannya. May the power supply circuit can be useful for readers, especially for friends who need a power supply circuit with the regulator transistor.

Simple Doubler Voltage 12 to 24Volt DC
This take place simple Doubler Voltage circuit, from voltage 12VDC to be 24VDC. By benefit Timer IC highly prevalent the come to NE555 and other equipment a modest again. It can make happen current contract in relation to 50mA fitting pro the circuit, with the intention of use low current the insignificant-sized.

The belief facility of the circuit be present, at what time use Volt input 12VDC give with the circuit long for converge Filter current smoothly with increasingly. The capacitors C5 give with IC1, The resistor R1,R2 and , capacitors C1, Which build the circuit ideal astable multi vibrator open place wave generator, by the side of the frequency with reference to 2KHz befall shown the way pin 3 of IC1. By take capacitors C3,C4 diode D1 and D2. Which build come to pass boost up voltage x 2,which self-control enhance the level Volt out be the sincere current about 24VDC or else 2 time of the level Volt input.

12 Volt DC Power Suplly Adaptor
This series of images you can apply to make an adapter or power suplly with the output voltage (V DC output 12V). Power supply in the only protected by a capacitor as a safety if the power supply is connected to the load on the circuit.

So I recommend using 35V capacitor with a minimum specification. The security of power supply to power the more we can menggunakkan transistor TIP, but I have not discussed it. To the diode bridge can be compiled from the 4 then you solder the diode bridge rectifier into one or you can buy a bridge rectifier so that the comb-shaped (sideways) or the box. At least I would suggest using a diode bridge 1 Ampere, in a series of adapters, the bigger the better course of ampere diode current in the circuit. Diodes like toll roads, and current as a car passing by. The larger and the width of the existing highway, the faster the flow of runs and through the circuit.
For the circuit power supply 5 V, you can change the volt regulator on the type 7805 and 7905. This application applies equally in this series. For variations such as fuse or circuit switch on / off you can try it yourself.

1 3 12 2 VDC Variable Power Supply
Power supply circuit to generate output below were variations between 1.3V DC to 12.2V DC with 1A current.

In addition, the power supply circuit is also equipped with over-current protection or shield against belebih flow. Power supply circuit is very simple, but the quality is quite good, made her basiccally regulator IC LM723 is a fairly legendary.

12 volt fluorescent lamp and transformer equipped
Valid schematic circuit diagrams of fluorescent lamps with a voltage source using 12 volt battery. This circuit 12 volt fluorescent lamp is very useful if the power goes out or can be used in a dark place with no electricity, but can use the battery 12V. This 12V fluorescent lamp circuit i have tried and the results are bright, durable until decades. You can use 12Volt fluorescent lamps up to 40W. Use quality 12 Volt fluorescent lamp, do not use the fast heat, because the fast was also damage the transistor at 12Volt fluorescent lamp circuit . Do not occasionally mistaken in putting up the transistor .

R1 = 220R/0.5W
R2 = 1/0.5W
C1 = 100n/100V
C2 = 220uF/50V
Q1 = D1885/D1710
A/B= To A fluorescent lamp/ and B to B fluorescent Lamp and just use one pin
B = Battery 12 volt with currents above 5A
Roll of copper wire on ferrite rod, with :
L1 = 1.2 mm diameter wire with many loops winding 20 times
L2 = 1.2mm diameter wire with many loops winding 20 times , and connected after the L1
L3 = 0.8mm diameter wire with many loops winding 500 times , connected after L2 and wrapped over L1 and L2.
F = Ferrite rod diameter of 10 mm
Number 1 - 4 in red will be connected to the winding.
