Wiring.  · Here a sample 3 Watt led driver circuit diagram, total 12 LEDs. Here 3 LEDs are connected in series, so the total forward voltage should be about Vx3 = V, and 4 such LED string connected in parallel. Each LED is of about mW, so total power should be around 3 watt and total current should be around www.doorway.ruted Reading Time: 2 mins.

The closest E12 value is 3,9 ohms, it will give you a constant current of mA. However you can't see any difference in the light output. If you use 3W LEDs, which has a current consumption of mA, the calculation should be: 1,25 divided by 0,7 makes 1, The closest E12 value is 1,8 ohms, the output will be mA. the formula is: LED current in amps = / R3 so for a current of mA, set R3 to ohms you'll need a power resistor usually, R3 power in watts = / R3 this circuit also has the drawback that the only way to use it with a micro-controller or PWM is to turn the entire thing on and off with a power FET. and the only way to change the LED brightness is to change R3, so refer to the earlier schematic for "circuit #5" which shows adding a low/high power switch in. regulator pinout: ADJ. led drivers 12v 3w are effective products useful in regulating power supply and providing uniform radiant output in electronic circuits. Goods ensure greater luminous efficacy and efficiency. led drivers 12v 3w on www.doorway.ru are appropriate to run with both AC and DC power supply. They find application in lighting, circuitry design, and onsite metering.
