12v dc power supply Customers Reviews

  • About what I expected

    posted by joshyboy

    Unit advertised as 240W, I needed 100W so thought even if it supplies half of rated output, it's good enough for my needs.Have tested it up to 120W no trouble, unit sits at about 60-70°C. Input power is about 150W at 120W out.Looked at DC output on Oscilloscope, very smooth and noise free (forgot to check input rail).
    Draws 45mA at idle with nothing connected. This may be significant for some.
    Pretty sure it will do what I bought it for, if it fails I will update review.
  • Very powerful

    Very powerful (4A). Easy to use.Connector standard in routers and others equipments (5.5 x 2.1mm plug).Usable on different equipments 12v (surveillance cameras, scanners, routers, led strips).
    Quality stuff, but has no power cord (standard computer cable). Perfect for anyone who is replacing a power source with problems. Works as it was expected, good and cheap choice!!!
    Usable on different equipments operating in 12v.
  • The average quality of the power supply.

    posted by Nez74

    Claimed output is adequate. The assembly is made qualitatively, nothing sticks out.
    Unknown frequency range of the pulse generator power supply. I thought I'd make noise isolation, but the hissing sound has decreased only slightly. After noise isolation a natural ventilation was not enough. The power supply began to overheat.
    To power the LED lamps in the living room is not suitable. I had to order another power source.
  • Works as expected

    Works as expected, good quality. I ordered it for a LED stripe. Even a non electrician as I can figure out where the cables go.
    For about the same price, I can get a PS for a PC rated 350W. I am not able to compare the qualities of both, but I should have considered this alternative. A PC PS has more parts, so I would expect a lower price here, but as I already said, I am not an electrician.
    Well, as I already mentioned, the PS for a PC might be a better deal.
