current source power supply Customers Reviews

  • excellent source of current

    posted by ustohal

    Excellent source of current. Provides constant current over a wide voltage range. I measured the range from 24V to 35V and the current was still exactly the same 320 mA. The source is pleasantly small, execution is precise. Insulated against water. When operating with a minimum of heat. I eat it with powering 10W 3200K LED module, function OK.
    Great little resource with a wide range of supply voltage. Ideal for LED applications from the 8 to 14 LEDs.
  • GOOD, But not exactly as described

    GoodBut not exactly as describedI received a product with different technical dataWalt is:12V-27V300MA
    Technical data was different than describedIn this case was that it was right for meBut it may not suit someone else
    If technical data all right with youIt's a good product,Looks quality,Reasonable price
  • Good quality, 7.4W output, 8.6 watt consumption

    posted by nagymate

    Small, good quality. High frequency output (LEDs will not flicker). Protected against too small resistance loading.Large input voltage range.
    While output power is around 7.4 Watts, consumption is 8.6 Watts (from 230V input voltage). This means 86% efficiency. Output voltage is vary depending on the loading to achieve almost constant current. In case of open circuit the output voltage is around 45 Volts.
    If You only need only 7.4 Watts and 86% efficiency, this product can be a good choice for You. You cannot use 10W 12V LED chips with this, because the lowest output voltage is higher than 12V
  • Dimmable 13~18 LED

    posted by johnyconny

    Hello allI drive to this review that I've found that a dimmable LED driver is not in the web shop is indicated as dimmable?It is item number 174475I compared it seemed to article number 171146Look at the pictures.
    I've tested this with the LED. DIY 7W 2800~3200K 560~630LM Round COB LED Module (DC 21~24V) With these 3 LEDs 7w (141851)These LEDs are beautiful in color temparature.
    I am probably going to bying more.
  • Its not 12V output it 24V

    posted by Hanina

    Low price, Build is OK, soft wiring, Small size easy to mount inside lemp or other unit, easy to wiring
    Can be nice if bottom PCB will be cover with protective plastic to avoid hazard from the 220V, I warp my device with adhesice plastic rebon isulator
    Spec is not correct the unit is 24 volot insted of 12 volt this cause LED it to heat up and eventualy blow.
