Dual voltage power supply circuit diagram. Lets try to understand the circuit description of each of the following assorted lm317 circuits. The operation basics and a schematic diagram of smps power supply for atx computer with power factor correction pfc. The circuit must provide sufficient current to light the led at the required brightness but must limit the current to prevent damaging the led. In electronics an led circuit or led driver is an electrical circuit used to power a light emitting diode led.
The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. Pulse forming network 1 and ssy1 trigger pcb description of pfn1 pfn1 manufacturer and model unidentified is a combination of a 36 uf 950 v energy storage capacitor 003 mh inductor automatic bleeder circuit and various connectors and other stuff. My plans are to make 2 pieces in two separate chassis and when i need dual voltage supply or voltage higher than 30v i will use both of them. A regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure.
1 create a 10v peak to peak voltage swing and 2 drive both positive and negative polaritiesa bipolar output can be handy if you need to drive a motor in both directions. Product folder sample buy technical documents tools software support community lm158 n lm258 n lm2904 n lm358 n snosbt3i january 2000revised december 2014. Please note that the diagram may show lm117 which has identical features and specs as lm317 thus both are interchangeable. There will be digital panel meters on the front of the chassis which i already ordered from ebay.
This power supply is great for powering all kinds of electronic projects.
