Simple 12V 2A DC power supply
Today, my son builds a simple 12V 2A DC power supply for a 12V solar pump. It is an Unregulated power supply because load is DC motor only. Note: More circuits 12V Power Supply How to works I teach son to understand the working principle of this projects. The main …
12V linear regulator for Transceiver Radio
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 …
12V 20Amp Power Supply by IC 7912 + 2N3055
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 …
