dc dc power converter Customers Reviews

  • Very good device

    posted by bitsnapper

    The converter is very easy to use after having understoof the dip switches. It offers good efficiency and doesn't get very hot at loads of about 1.5 amps.
    If you are familiar with voltage converters, it should be no problem to use it. Just connect a voltage meter to the output and see what happens if you use the dip switches to adjust the output.
    Very useful and reliable for any purpose. I used it for supplying a reduced voltage of 8 V to the red part of a RGB LED chip in combination wit a self made RGBW controller. Works better than a resistor for current control.
  • Exactly what I wanted

    posted by mythic1

    -Easy to use even for novices-Wires are ready to solder-2 ears to get it fixed tight-15w output power (5V, 3A), sufficient to power a dash camera, etc.-Quality feel-All the details you need are written on product-Very well sealed against dirt or dust-Small enough to hide it under the dash
    -Ideal converter with sufficient power output. Ideal for powering any gadget for your car
    -I recommend it. Other products around, for the same price, you get maximum 10w output power.
  • 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.
  • Switching Regulator

    posted by Logsplitter

    A simple device, no external components required. Output ripple is very low, as is heat as full output. No heatsink necessary even at continuous full output, (with 15 volts supply voltage).
    The regulators can be combined with steering diodes to increase output current. The ripple does not appear to increase even when combining the output of 3 regulators.
    An excellent stand alone regulator, especially for a USB power source. Have used more than a dozen for automotive cellphone chargers without a single failure
  • Used as electronic DIY connector

    smal part .very uselfull to have around.come in pair (male+female)
    used not only for cctv in fact.uselfull to have screw in a able.so you do not need to cut the cable to have solder free connecto to power one of your electronic experiment.yes it s true wll plug are esylly found in the cupboard you stock your old part.But in the repair basket it's smaller so you have virtually a power apater everywher. (example sunday 10 pm zilion hundred km from home)...;)
    nothing to add ;)
