power supply driver Customers Reviews

  • Works well but produces sound

    posted by akonstantinov

    Small. Works. No heating noticed so probably efficiency is good. Powers 1 1W LED nicely.
    I will try to use some compound on transformer. Maybe that will silence it.
    It should use high conversion frequency to avoid buzz.------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------
  • Perfect for small projects

    posted by RacerXGT0

    Excellent price, very small size and build quality looks good.
    Drive 3 x 1watt LED's in a series exactly.
    I live in the USA so the 120 volt A/C color coding on this unit is setup for for European spec. All I did was match the HOT and NEUTRAL lines accordingly.
    USA: Black = Hot, White = Neutral
    EUR: Brown = Hot, Blue = Neutral
    This is great for small projects, though if building a multiple LED project with more than 3 LED's, better order more!
    This little LED driver is a winner, allows you to build very bright LED lighting for your home at a low price.
  • small dc-dc converter

    posted by nuralist

    The device was bought for powering Cree xml diode to limit current. The device have Voltage and Current regulation. My diode takes 3 ampers of current so I had to use little radiator with a thermal grease on the LM microchip, without it temperature was more than 100 C and LM chip protection had tripped. After i've used heat sink everythink became OK)
    informative specification
    good deal
  • Very good DC-DC Converter !

    posted by Warnings

    - No noise- Can reach really 35V from 25V- Stable voltage (can use 12 or 24V DC, you have the same output)- The green part is removable for put more easily the cables- Chips are screwed on the case for dissipate heat
    Box size : 71 x 44 x 25 mm (LxWxH)Box with screw part size : 91 x 44 x 25 mm (LxWxH)
    It's a good product and can be better if you change the two capacitor ;)
