This article describes the Regulator 0-30V 1A By Transistor CIRCUIT (H1061). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:H1061.

This is simple dc voltage Variable regulator Circuit. I use the transistor 2SC1061 or H1061. It used for control current up to 1 Amp. The circuit use transistor 3 pcs only, it very small circuit. The Q3-C1061 must hole heat sink with. VR1 for control voltage 0-30V at 1A

The details
This circuit is easily designed for beginners to learn the operation of the regulated output circuit, because a majority of the circuits in now often made of the IC packages, which some of you might not like. When before we used the transistor circuit,
We readily can buy the equipments, cheap and be adapted easily substitute another number.
In addition when they are damaged you can repair with replacement the parts some pieces only, not need to replace them all with the same as the ICs.

In this circuit is designed be A series REGULATOR form that has very performance, you change the voltage output 0V to 30V by adjust the Potentiometer – VR1-10K, so it is controller a bias voltage of the transistor Q2-BC337.

The parts of circuit
R1,R2________10K 1/4W Resistors
R3,R4________100ohm 1/4W Resistors
C1_________1000μF 35V Electrolytic Capacitors
C2,C3_________100μF 35V Electrolytic Capacitors
Q1,Q2__________BC337 50V 800mA NPN Transistor
Q3__________2SC1061 or TIP41 or H1061 or MJE3055 50V 2A NPN Transistor
D1-D5__________1N4002 100V 1A Diode

Making this project
- Put the complete equipment correctly by the circuit.
- Enter the power into circuit, then uses a voltmeter measure the voltage output.
- Adjust the VR1, then notice meter should be changed as required.
- Try to connect the load to the circuit, The output voltage should be adjusted to a constant does not change.
- The Q3 should be equipped with a cooling medium size.

DC Supply adjustable Voltage 0-20V at 1A

Today a friend comes to see at a house lead electronics old equipment come to amount of. He consults me that what is set equipment should build electronics project ? good. I then advise that try build DC Supply adjustable Voltage Circuit. all right by can fine voltage get , 0-20V at 1A max . Convenient for the circuit experiences general at want tall quality little because be model Regulated with. My friend will think to apply with Pre tone Amplifier Circuit, at use the transistor also. By you can use the transistor can replace many the number such as number TIP41 or TIP31 , or H1061 or C1061 or MJE3055. Fining decorates VR1 -5K make Voltage output modify from 0V to 20V. Besides should use a pot transforms the sky 2A sizes. Will have then current output 1A min. The detail is other see in the circuit sir.
