Worked perfectly last week by bode verified purchaser For my application I required 25 mA so I removed the two 0.3 resistors and threw in a 10 that I had lying Like our official Perel & Toolland Facebook page!

can i use 10mm LED for this circuit? Showing results with star rating. Published on Aug 1, 2013High power LEDs differ from regular LEDs in a number of respects. http://www.instructables.com/id/Super-simple-high-power-LED-driver/ Adding a 56 Ohm resistor at the input helps to introduce some damage control measures, but still it alone cannot do the complete safeguarding of the involved electronics.

As far as efficiency goes, I don't know. or also you could connect it to PWM (the simple PWM could make with 555 ic, but it could only give you 1A current with 4-15V input0... Altogether, this means that you need a switching regulator designed to generate a constant current instead of a constant voltage.DeleteSwagatamAugust 19, 2012 at 7:15 PMI tried to explore over the net 10 Watt Led Driver Circuit Diagram

Would I wire everything in series, with the fan being the first to get power?

Firstly, current regulation using resistors is impractical so it's necessary to use a switched mode voltage and current regulator. Output: DC12-25V, 300MA -5%.

Led Driver Calculator Thus, I want to drive 50 parallel strings of 10 using a meanwell driver rated at about 40 watts? (The 500 little leds would consume 30 watts at 1amp at 30v).

Things to consider before selecting an LED driver What type of LEDs are being used and how many? The data sheet says 6 volt minimum, but the tutorial video says 7. Michal A. Cancel Unsubscribe Working...

i can use of NPN Transistor, 2nd question is that do i must need to use a Transistor Heat Sink with it or not????I need to make the circuit sealed and is it correct? AC Dimming For high voltage AC power drivers there are a couple options for dimming as well depending on your driver. Many AC driver work with 0-10V dimming, like we went over Bhagat ReplyDeleteRepliesSwagatamOctober 17, 2012 at 8:22 PMThanks Pratik!I appreciate your knowledge!Since the current is nowhere near the 350mA mark, the LED in the above circuit will never get hot, so a

For which department?

DeleteSwagatamSeptember 19, 2012 at 6:10 PMNo, the broken link indicates that the wires are NOT touching each other, rather are overlapping. pl check capacitor voltage and mA chart on internet. 1uF capacitor supplies only 40 mA. I’m very curious if this would be a suitable idea or this is merely a terrible, horrible, & foolish idea. what could be the problem?Thanks,DeleteSwagatamMay 20, 2012 at 11:28 AMIf it's too bright you can reduce it by adding a resistance in series with the LED, use a 100 Ohm 1
