  • Nice Driver, but did not work well

    posted by logologo on 17:05:38 G2T 19/02/2014 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: You can see what is inside. No SMD Chips, you can follow every powerline. its easy to use, because you can change everything on this driver. the cables are quite good

    Cons: first of all i have testet this driver about his current. and there is the first problem. it does not have 900mA. my driver is just running at 500mA. at the very first beginning it was running at 400mA and increase to 500mA within one hour. maybe i had stray bullet. i dont know.

    Other: maybe i will reorder and check the current again.

  • Aquarium LED Driver...

    posted by wampyz on 16:17:00 G5T 07/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - universal compact switching constant high current driver - drives many of the 3x3 high output LEDs at 90% power leaving a 10% safety margin - very little heat generation

    Cons: - no safety casing - no mounting holes - can't alter current output - could be cheaper

    Other: great component if you're thinking of retrofitting your aquarium lighting...

  • Great LED driver!!

    posted by badmat on 17:31:55 G1T 05/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - High Quality switched current source LED driver - Small, can be hidden very easily.

    Cons: - One of them had a buzz when connected to the power supply without load. But no buzz when connected to the load. - No other real cons that I can think.

    Other: - If you need current source to drive 12v LEDs this is the product for you!

  • Very good LED driver

    posted by FreddyPL on 12:22:00 G12T 22/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Switch mode so efficient, less heat. Compact size. Isolated output. Small and easy to use.

    Cons: No protective casing. Depending on application this can be either good or bad. In my opinion it's good. I can use it at many LED driver.

    Other: Good driver, especially for its price. I recommend this driver to everybody who needs small switched power supply with 12V output and 500-900 mA load

    posted by anitas on 07:17:09 G10T 02/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 1. Dirt cheap (I bought 6 with bulk rate) 2. Isolated DC/No electrocution on LED side. 3. Switch mode so efficient, less heat. 4. Compact size.

    Cons: No holes for mounting. Components and pcb traces are at the edge of pcb, so chances of short with if not taken care of.

    Other: Good performer at this price. A envelop box may require by someone, however this makes it bulkier and, heat convection stops. I think mounting holes should be provided.

  • A very good LED driver

    posted by CCOnn on 22:20:35 G6T 01/06/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: -For the price, I will be very hard-pressed to find similar drivers elsewhere. -Runs to a true 900mA. Some other drivers on DX do not run true to published ratings. -Small and easy to incorporate to many designs -So easy to use, it's almost plug and play; though you must connect the wires first of course

    Cons: -No protective casing. Depending on application this can be either good or bad.. Since in some designs the driver will be placed in a dedicated protected spot a casing would have been a waste... Furthermore losing the case means the driver is cheaper.

    Other: Certainly the choice for LED lighting projects requiring ~10W power. Fully satisfied with this driver and will get more in the near future!!

  • serves to what was done

    posted by Ramatys on 21:22:56 G4T 04/04/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Answers to what was done, no heat, no noise and good weld quality.

    Cons: Coal wiring and mounting of components on the board as a tanqto fragile, stir carefully and be careful because it has no insulation in the weld.

    Other: I believe it has a better cost benefit with this set suggested, and that is better than buying the driver with cash. More worthwhile.

    posted by kde11 on 16:27:41 G6T 23/06/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Price; - Switched power supply (high efficiency); - Good build quality; - DC output is electrically isolated from AC input; - Driver doesn't burn out if powered on without workload (although I didn't test it in this mode for a long time) - Noiseless; - Doen't produce too much heat even when continiously loaded (no need for any heat dissipator).

    Cons: - No direct control of the output voltage/current. The inverse feedback is done through the coil that is used to produce oscillations (not through the output coil); - No mounting holes.

    Other: Good driver, especially for its price. Also I've added 24 Ohm resistor in series with the AC input to reduce input rectifier peak load when connecting the driver to the AC power supply (this also removes a lot of sparks when inserting plug into the wall socket). While working, this resistor consumes only 2 V of input voltage, so I recommend everybody to modify the driver this way (10 - 20 Ohms is OK for it). I recommend this driver to everybody who needs small switched power supply with 12V output and 500-900 mA load. Hope it will last long.

  • Seems to work in parallel

    posted by zlp00 on 23:18:09 G1T 08/01/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I am using 2 of these drivers in parallel to drive a string of three P7 emitters. (This technique supplies less current than the P7 max ratings, but I have limited heat-sinking in my application, and it seems to be the only AC-powered option on DX at the moment.) Some LED drivers are not stable when multiple units are combined in parallel. This one appears to be. It's been running for a few hours and the drivers are no hotter than when I use them individually. I haven't measured the combined current but I have quickly switched from 1 to 2 drivers and the difference in light output seems to indicate that 2 drivers successfully deliver double the current.

    Cons: No protective case. As others have noted, you can shrink-wrap the whole thing (using the big heat-shrink tubing used for battery packs)

    Other: Great driver, as are all of the DX constant current drivers I've tried so far.

    posted by solar5 on 21:38:30 G9T 04/09/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Price: 5
    For a 10w power supply you can't beat the price. This unit produces a smooth and pure flicker-free DC power. So I rated it a 5 on price.
    Ease of use: 5
    I gave it a 5 also. Connect the yellow wires to a 110v ac outlet and the red and black wires to the load, as in my case, (16 1-watt LEDs, (sku #13612 XM050YW050A 1W 50-Lumen 3000K White LED), and your in business. Simple!
    Build quality: I rated it a 4.
    The reason for a 4 rating is because the unit has no protective casing or mounting holes. All electronics are exposed. Next I will buy a plastic case in which to mount it in, problem solved.
    Usefulness: I rated it a 5.
    I am powering 16 1-watt LEDs in a series-parallel configuration, and it is just warm to the touch, and the LEDs are warm also and too bright to look at. More than enough power for the job.
    Overall Rating: 5
    Because overall, it is a great power supply. It does what it is supposed to do and it does it well.

    Cons: As mentioned above, "No protective casing".
    Other than that, None.

    Other: Bottom line, I will buy this unit again. Anytime I need 10 watts of good quality dc power, I know this unit will deliver.
