Essential for those who want to use the radio transmitters from a car to use in your home is you need a ham radio power supply DC-12V or DC-13.8V with enough power out of 5A to 30A. According to size of the a transmitter. I highly recommend this high-current power supply circuit. Because good performance, […]

This be DC power supply regulator circuit be simple. That can give voltage come out 12V and 5V by use part base be Transistor 2N3055 and Zener Diode 12V. Make can take volt can reach about 15V maintain one’s position voltage be stable 12V well. And change the integrated circuit LM309 for regulate about 5V […]

This circuit is 12V linear regulator for the receiver radios model transistor. which with regard to often use current the very. Especially when do signalling . The 2N3055 transistors that use in place circuit s pay electric this power. Then must pay the electric current has very much. For a resister R1 in the circuit […]

Here is 12 volt power supply 20A , USE LM7912 and 2N3055 . It easy circuit , Low cost. see detail more in image. This power supply is the result of the use of components at hand (junk box). The core of the project is a number of 2N3055 transistors and a transformer with a […]

The basic car electrical system gives you around 12-13V when the engine is off and 13-14V when it is running. Not good for a computer, so the basic idea is to use a simple voltage regulator which takes an unregulated voltage in and outputs a regulated voltage. The LM1084IT-12 is a 12V, 5A, Low dropout […]
