power supply green Customers Reviews

  • Good quality LED driver

    posted by smv1210

    Good schematic, high quality components are used.Protection against the load short circuit or breakage does work quite OK.
    Output voltage (DC 30~36V) information can confuse some potential purchasers/users. In fact, output voltage range is much more wider: 20~36V at least. The usage of TSM101AI in the driver's output voltage/current control schematic, means, that some experienced users can even implement (an analog) dimming there ;)
    Good product for its money!
  • Great little gadget

    The board is great. Powerful enough, it is small and compact switch mode power supply. I have used it as a LED stripe driver (for 1m of LED stripe) and as small audio system power supply. For the last one - it is very quiet, the EMI circuit does it's job. The holes make it easy to install.

    A very good and usefull SMPS. I really recommend it.
  • Fast delivery, works well and value for money

    I ordered this power booster on 28th Nov and I received it on 6th Dec in good condition. Took slight more than 1 week which is consider very fast.I connected the input to my 12V DC battery which is charged up by solar panels. I adjusted the output to 17.2V to charge my Philips electric shaver. I measured the actual voltage using Digital multimeter and found it to be 17.13V which is close enough.The stands are in rubble which help to prevent from short circuit. The LED display is bright and clear.
    It would be good if it comes with plastic enclosure.
    Fast delivery, good product that suits my needs.Highly recommended.
  • Really small!

    This is a really small switching power supply!!Line side has a varistor, thus some kind of surge suppression is provided.Output voltage: 5.10V (no load)When no load is attached, a witched power supply draws about NOTHING current. Ideal green replacement for those old bulky transformers.
    Still didn't measure ripple at maximum load (will put results soon), but according the specs it is around 150mV (according the specs it is 150 mW, but that is probabely a bug...)
    Nice, cheap and small switching power supply.Not worth making one youself......
