  • nice driver for several uses.

    posted by lasermanathome

    sure , you can use them for Cree leds etc.But the single mode makes it possible to use them for other functions too.I have used them for 455-445nM laserleds, those nasty bleu powerbeam LD's with over ONE WATT bleu laserlight.Those laserleds can easily be destroyed, this PC prohibits this and crank your LD up to its max without obvercurrent.
    You have to use them with LD or leds wich are in voltage near white powerleds(3-4V)Almost no heating up or instability in current.
    Nice PC for inventors, in theory you can put them parallel but diode for safety is advised.
  • Excellent DIY LED driver

    - Great price (especially the bulk rate)- High quality current output: I've used over a dozen of these drivers and they all provide a very constant current, and thus flicker-less LED lighting- Can be dimmed. The integrated circuit for this LED driver is the PT4115 LED controller, which contains a "DIM" input. Applying a pulse-width modified digital signal, or a variable DC voltage to this DIM input provides continuously-variable dimming of the LED. For more information on how to do this, see the PT4115 datasheet (it is very easy to read, so even a beginner DIYer should be able to do it).- Open-circuit protection: this driver will not be destroyed if it is not connected to a load when powered (this can happen to some LED drivers)- Thermal protection: the circuit will protect itself if it gets too hot- Highly efficient: the PT4115 is up to 97% efficient, so very little power is wasted- With a few modifications, it can output up to 1.2A at up to 30V, for a total power output of over 30W (this can be done by simply changing the resistor and inductor on the circuit. See the PT4115 datasheet for info on how to do this). This means that this driver can power LEDs up to 30W, although the inductor required for such high outputs would be a bit big for the circuit board.- Can be powered by either AC or DC voltage (but note that its maximum input voltage is NOT 40V, as stated in the product title. See my con section below for more info).
    - If you're using a DC power source and you want to maximize the efficiency of this LED driver then I recommend removing the rectifying diodes because these waste a bit of power due to their forward voltage drop.- Note that the large, unbendable metal prongs (which are the input voltage connections) can be easily removed and replaced with something that is easier to deal with (and to bend), such as wire.
    Excellent price and highly modifiable. Highly recommended for all 1W LEDs. Also has the excellent benefit of being dimmable with slight modifications.
  • Great driver for high power LEDs

    This is a really nice driver for high-power LEDs. I use it to drive Luxeon Endor Stars. It delivers 300mA to 350mA to the Endor Stars which are wired with three high-power LEDs in series. I run it off of my 12V car battery.Unlike resistors or voltage regulators it wastes very little power. It is very much like the Buck Puck drivers that cost$15. It's very simple to use it will run on DC (any polarity) or AC. The chip used in this drive is a PT4115.
    This driver will work with any set of LEDs which all have the same 300mA current requirement.Just put them in series andd hook em up.BUY IT
  • very good reliable driver

    - easy to use- easy to solder- delivers 1.4A to led- 1 mode perfect for simple designs and retrofitting in old lights.
    easy to solder. small diameter fits in many old lights. perfect for updating old lights. straightforward use. no problems with soldering. I used it for an xml led and it delivers 1.4Amps to the led. The use was with no problems and the driver works without geting too hot.
    nice driver. veru useful. easy to use. I expect a 1-mode 2.0A version...

    Small, easy to use, more efficient than it's small brother 1x1W. Using E27 DIY bulb and MR11 triple mcpcb & optics you can make 3x1W bulb for 20$.
    IN 30,15 mA @ 224,53V => 6,76 W
    OUT 309,5 mA @ 9,54V => 2,95 W
    Eff : 43%
    When it will achieve 80% efficiency it will be the straight way to LED based home lightning. Now it's god for fun, experiments and LED maniacs.
