  • Best power supply i could find for this low price

    posted by Rakkachi

    It is a small practical power supply unit, the connections are clearly marked out on the PCB. On one side there's the live/neutral input while on the other end there's the +/ground output. The solderwork on it is very good, not messy at all. The components used look solid and of medium to high quality.
    ideal for small projects that need a reliable power supply.
    small yet powerfull power supply unit.
  • Good buy if you need to use USB power on your breadboard

    posted by Aireal

    Can use both 3.3 and 5 volts at the same time. Just had to figure out how the jumpers work. (Not to hard, but no instructions) Takes both USB and barrel connectors although never connect at the same time!
    I recieved a different one to the picture shown here, but it is probably better, with more pins to the breadboard.
    Get one if you need it.
  • Breadboard powersupply

    posted by koj3000

    Fits perfectly on my breadboard, and you can choose one bus in 5V and the other to 3.3V at the same time, it's very useful on my project.I've powered it trough usb and with the power socket (not in the same time) and it works.The power button is nice because it's works when you connecting it to power trough usb or power socket.There are connector upon it to connect with breadboard cables another device.
    None.
    Great product for a cheap price. To recommend.
  • 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
  • Really small!

    posted by Polonium

    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......
