Hello guys just another newbie question .. so im new with all this suff and i want to make dimmable power leds so i ordered some power supply from ebay but they ofc like allways send the wrong one to me istead of 12v they send me 24v power supply. so my plan was i would somehow use some kind of mosfet with potmeter and this driver to run my 3w leds and make then dimmable so im wondering is there big differnece if i use 24v or 12v ..!
power supply is
its says thats its Dimmable via low voltage LED Dimmer .. what that mean ?
With a 12V supply you would probably wire 3 leds in series. With a 24V supply you would wire 6 leds in series, maybe 7.
Post a link to the power supply you received, and the leds you plan to use, and we will check.
Yes, post the LEDs. 3W LEDs are likely to need a current controlled driver, and not just a simple resistor.
A LED driver like what's found on this board
power supply (http://www.ebay.co.uk/itm/251282689468?_trksid=p2057872.m2749.l2649&var=550300721283&ssPageName=STRK%3AMEBIDX%3AIT)
this is power supply and these are leds..
I don't think that power supply is suitable for those leds. The power supply is constant voltage. It is suitable for 12V led strips. Those leds need a constant current power supply.
