Simple 12V 2A DC power supply
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 principle, we use this project to reduce voltage from AC-line 220V to 12V DC. On Figure 1 The AC 220V 50HZ is connected to the circuit through S1- ON-OFF switch and F1-fuse to protect this circuit. Then they flows through a 2A transformer to reduce voltage into 12V AC. Next,through …
12V linear regulator for Transceiver Radio
Power supply
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 will perform to decrease the quantity will of the electric power to will lose to go to down and make can use cheap transistor get . And in value filtration R1. As a result have Voltage fall straddle all about 2 Volt. The Zener Diode …
