5 Volt Switching Regulator Power Supply

The switching regulator power supply used LM2575-5.0 on this schematic. You can make the stable voltage by using the 3 terminal regulator like LM317. However, because the output electric current and the inputted electric current are the same approximately, the difference between the input electric power (The input voltage x The input electric current) and the output power (The output voltage x The output current) is consumed as the heat with the regulator. Because it is, the efficiency isn't good.

2N3055 using ic 5 Volt Linear power supply regulator

This is 5 Volt Linear power supply regulator circuit. It uses electronics part that seek easily have no zener diode , and the integrated circuit use Transistor 2N3055 and other. Which seek easily use diode perform heal voltage be stable. By diode 1N914 number uses 1N4148 number can replace. For Transistor 2N3417 use the number BD139 equiv get. If use Transformer 1-2A circuit be this size give current get about 1 Amp. Friends may don’t be bored with line this circuit. I thinks it may advantage seek part easy and economize good yes.

16 × 2 LCD Volt Meter Ampere Meter With PIC

Volt meters & ampere meter with PIC can be used to measure voltage and current simultaneously. The series of volt meters & ampere meter with PIC16F876A PIC is used as a data processor voltage and current are measured.

This circuit uses the viewer in the form of 16 × 2 LCD used for the data display voltage and current measurements. In the article volt meter and ampere meter with PIC are discussed kerannya limited to devices only. More detail can be seen from the image sequence volt meter and ampere meter with PIC below.

12 Volt 2 A Switching Power Supply Wiring diagram Schematic

This is a Simple 12 Volt / 2 A Switching Power Supply Circuit Diagram. The schema 12 volt / 2 A switching power supply in the above scheme is not too complicated. At the output of this block provides a stable 12 V and maximum current 2A. Power supply units are quite compact and is suitable for debugging schemes, as well as a permanent resource for stationary devices, including power for the logic electronics for the home-made CNC machine tools.

12 Volt / 2 A Switching Power Supply Circuit Diagram

Transformer is available in the free market and avoids the hassle of having to self-winding. The diode bridge BR 1 of any given voltage and current of 2A. All other elements in the high part of the schema are designed by the same voltage, taking into account the mains. The scheme of 12 volt / 2 A switching power supply operates from the high voltage network, to be observed when mounting accuracy and caution when using. It is desirable to block the finished board to “pack” in the body.

Regulated 12 Volt Supply Wiring diagram Schematic

This schema above uses a 13 volt zener diode, D2 which provides the voltage regulation. Aprroximately 0.7 Volts are dropped across the transistors b-e junction, leaving a higher current 12.3 Volt output supply. This schema can supply loads of up to 500 mA. This schema is also known as an amplified zener schema.
