Cheap adjustable  0-30V 2A Laboratory DC Power Supply
Power supply
This 0-30V power supply is the variable voltage Regulator at 2A max, by used IC-723 for control volt stable regulated. The 2N3055 power transistor for boost up current to 2 Amp. It suitable for general electronics work shop. Because it is a simple circuit and easy circuit. In addition to this has the over current protection as well. This circuit is designed using LM723 voltage regulators IC –DIP 20pin maintain a constant voltage, and a power transistor as the way through the current to can be used up as wanted. The circuit was designed also with overload protection or short …
My first Variable DC Power Supply 1.2V to 30V 1A by LM317
Mini Projects
If you are beginner in electronics and you want to have a great power supply. This project is design for you. It can supply voltage 1.2V to 30V at all range is 1A. New update Please read below this article. This is the First DC power supply in my life that made to use in many projects. It is ideal for those who want to adjust voltage from 1.25V to 30V and currents up to 1A. Which is sufficient for normal use Such as is power supply instead of an one 1.5V AA battery or when you want to listen …
Bench variable power supply 0-30V
Basic Circuits
Today I seeks variable power supply circuit come to deposit again. Which be the circuit that use base equipment, build not difficult follow the circuit can fine volt get 0-30V , give current get about 1-2A depend on transformer at you choose to use. The prominent point of the circuit use transistor join a pin BE replace Zener Diode. Then get around problems about seek buy Zener voltage that can’t want. By transistor at use 2N3638 numbers or the number replaces. For transistor output use 2N3055 durable numbers current not exceed 2A. For other detail , request friends , see …
