12V 2A LED Power Supply test with schematic In this video I test a Chinese 12V "2A" switching power supply designed for LEDs, CCTV, routers, etc. It cost me only $ 1.80 including shipping. Simple 12V 1A LED Power Supply with schematic and transformer autopsy I took a look at the board layout, reverse engineered the relatively simple schematic of it and made an autopsy of the transformer. This power supply is quite dodgy there's no fuse, no EMI ... Circuit Diagram Of Smps Power Supply Like other power supplies, switch mode power supply is a complicated circuit that supplies the power from a source to loads. Switch mode power supply is necessary for power consuming electrical & electronic appliances & even for preparing electrical & electronic projects.

Power LED Driver Circuit Electronics DIY Here's a really simple and inexpensive Power LED driver circuit. The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you use or surrounding environmental conditions you subject the LED's to. Simple LED Circuit ElectroSchematics We start by showing you the LED circuit in series with a resistor. You must make some calculations to figure out the resistor value, depending on voltage power supply, LED voltage drop and desired current. LED Tutorials Proper Power Supply for your LED Project LED Tutorials Power Supply The power supply, also known as a transformer or driver, is one of the most important components of an LED system. Using the wrong type of power supply can not only damage your LED product but can also be a very dangerous fire hazard. High Power LED Driver Circuits: 12 Steps (with Pictures) Q2 acts as a variable resistor, stepping down the voltage from the power supply to match the need of the LED's. so Q2 will need a heatsink if there is a high LED current or if the power source voltage is a lot higher than the LED string voltage. (Q2 power = dropped volts * LED current). Q2 can only handle 2 3 watt before you need some kind of heatsink. with a large heatsink, this circuit can ... 0 30 Vdc Stabilized Power Supply with Current Control 0 ... I had just built today this power supply using the schematic and pcb lay out and everything works fine,maybe you have a bad solder or some parts are wrongly placed, recheck all connections and all soldered points it should looks shiny if properly soldered. Power LED's Simplest Light With Constant current Circuit ... Here's a really simple and inexpensive ($1) LED driver circuit.
