  • Great for testing and easy to modify

    posted by pmatil on 06:15:59 G8T 29/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Cheap, has good quality MR16 pins, good silicone wires, small

    Cons: The input cap is useless. With the original cap I got 55 % efficacy with 2 blue leds and 12 V input (1 A output current). The inductor also gets quite hot. The dimming pin should maybe have soldering pad.

    Other: Good for the price and fits straight into some DX MR16 housings.

    posted by bls123 on 12:43:32 G8T 09/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Small, lightweight and easy to modify for just about any use. Has very good current regulation that only varies 5-10ma at most over the total operating range. The units single resistor that sets the current level is easy to change. Input has a bridge rectifier so polarity independent and can be fed from either an AC or DC power source. Bridge rectifier diodes are easy to remove for greater efficiency when powering from a DC source. Uses a PT4115 chip. This makes the max input voltage 40VDC (or about 28V AC) so up to 10-11 LEDs in series can be powered (depending on which LEDs are used and the total LED voltage required of course). Input capacitor is only rated for 25V however so must be replaced for higher voltages.

    Cons: None (for me at least. Some have complained about the wires being too short, etc. but for my use I remove the wires, GU10 pins, bridge rectifier diodes and cut the board away where the diodes were to make it even smaller.

    Other: I buy a number of which ever (13553, 13555 or 13557) is least expensive at the time for projects and simply replace the resistor when a different current level is needed.

  • Nice in series, bad in parallel

    posted by FabianKnapp87 on 11:44:57 G3T 18/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - PT4115 with standard wiring. - So it has capabilities for dimming - small - price is very nice

    Cons: - PT4115 is not useful for use them in parallel at the output.

    Other: Some pieces are at the maximum ratings at this board, but its cheap and easy to modify.

  • Very good Powtech PT4115 based LED driver

    posted by Jondo76 on 11:27:26 G1T 19/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Can handle many LEDs in series. - Good quality PCB - Efficiency is high, measured 96% (25 V input, 24V LED output) without rectifier. - Uses Rubycon japanese capacitor - Analog or PWM dimmable (if you can solder small things) - Reliable, I have been running them for thousands of hours.

    Cons: - Not 40V as specified, the chip can handle up to 30V and the cap on the board is good for 25V. - The dim input on the driver chip is not connected, would be nice with a solder pad for this.

    Other: Very good value

  • A nice PT4115 driver that can drive way more

    posted by oinkwaste on 15:53:39 G1T 10/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: PT4115 is a very versatile chip that can be supplied up to 30V. So considering you change the capacitor to something like 35V-50V, you can drive 7-8 3W leds with this beast. isnt it amazing? also the price you can get it is so cheap, it sometimes doesnt worth to make it yourself. In small quantities sourcing the PT4115 and the extra components can be more expensive

    Cons: not really a con but if you plan not to use AC, its better to tear the 4 schottky diodes that act as a bridge rectifier.

    Other: Its so versatile a chip that you definitely dont have to look further when you want to drive 2-7 3W leds :)

    posted by Infratuna on 10:46:43 G10T 24/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Building quality seems good. Does what promised and little more - it works with my bicycle dynamo which produce 6 V max. One of my GU10 230 V 3W led lamps driver broke down. I change this driver to the lamp and now I use it in my bicycle! It perfect cause it has rectifier and bicycle dynamos normally produce AC. I'm so excited :D

    Cons: If the product is good many people write here "No cons at until now. Could be cheaper". I have no idea how much this should cost. The price is ok for me. From local electronic shop this would be many times more expensive.

    Other: Nice deal! Hope it has a long lifetime.

  • PowTech PT4115 based LED driver module

    posted by al1alex on 04:54:10 G10T 07/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Small, very easy to use driver. Based on well-known PT4115 chip so it will be easy to change output current (up to 1.5A) or add dimming wire Works nice with 2 LEDs starting from 6.1VDC (with 5.55 V output)/ Can accept DC and AC - no problem with wrong polarity. Will be used for bike headlight.

    Cons: M16 legs too thick and solded on PCB surface. Broke one leg while inserting driver :( It would be better if the legs were soldered in metalized holes. DIM pin not wired.

    Other: Great product for bike headlight. Plan to buy more for friends.

  • Very small device, easy to use!

    posted by phett on 07:14:41 G6T 04/06/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It works very well in a wide range of voltage.
    Can be dimmed with some small modification.

    Cons: Dim-Pin is not made available on the PCB, but its not that difficult to add a wire for dimming.

    Other: The self-mounted dim only accepts 5V-input! Don't kill your device! The regulator is very small, so you need some practice to add a thin wire for the dimming.

  • great for lots of different applications

    posted by thecoolkidjoe on 04:33:59 G5T 16/05/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: this thing is great i use it on my honda xr400 for the head light. i have 2 running on just the stator power and it does exactly what i want. the stater puts anywhere from about 9-15volts ac so i left the bridge in because i dont have any reason for rf signals.

    Cons: some cons of this product are that it gets hot but as long as you take and put it on a very small heat sink you should have no problems also i would not put it up to 40 volts ac or dc it get super hot and starts to fail and melt. but maybe thats just the ones i got. another thing that would have been nice is a little wiring diagram or something to tell me what was what because once i got it i had to come back online and look for it.

    Other: great product and i will be buying more in the future

  • Most perfect LED Driver on DX!!

    posted by Iceananas on 07:06:07 G3T 02/03/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - PowTech PT4115: extremely easy to mod for your own purpose: change the sense resistor to vary your average current, you can also add a potentiometer or PWN module to dim your LED :-O - Can handle AC and DC, I didnt remove the bridge rectifier for the case I have to use AC. Although the efficiency will suffer, its the better solution for me. - Wiiiiiide input range. I wont go over 24VDC because of the small input capacitor, but anyway, there ist no better driver to build your 12V/24V LED project. Notice the input voltage must be higher than the summarized LED Vf.

    Cons: - RF interferences. But you can solve this easily: Just solder a capacitor to the board at the output pins (where Led+ and LED- is). I chose a small 16V 220µF and it is already sufficient at 12VDC input. I can listen to FM radio next to the driver. - Small input capacotor, mine has only 100µF/25V. Not relevant for DC, but will not be able to supply multiple LEDs in series at AC. Replacing it with a new one is easy. For calculations see threads below.

    Other: I removed the long MR16 pins to get it smaller. Get a small solder iron for the small parts (e.g. if you want to solder a pot to the chip). For me the most perfect driver I ever got.
