  • 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......
  • A delightful experience

    Does EXACTLY what it promises. * It is very, very tiny and lightweight * It performs well, the voltage is 5.20V* It is easy to use
    Highly recommended for just about any purpose you might have. I do not use it for helicopters or other toys; it is simply feeding 5V from a 12V battery to a 3G/WLAN router which is in a place where the mains power is not available.
    Good product, absolutely worth the price.
  • Compact power supply

    posted by jlramirez

    Power supply well built, sturdy and really delivers the marked current in the case. When loads 3,5 amperes the voltage don't drop down. The oputput voltage are regulated with a variable resistor, is useful but not necesary.
    Well ventilated case, if the power supply is heated, you can add a little blower. You need to put some spacer in the bootom of the case, you can buy in Dx.I will add a 12 volts PS SKU: 163956 to make a good power supply to my electronic laboratoy
    Good device to mount a little laboratory or made some electronics stuff
  • 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.
  • Really nice relay controller

    posted by Cimistus

    Looks really well built. USB side is quite well insulated from the relays, so using even high voltages shouldn't be a risk.
    Suitable case may be an issue, but then again, DYI cases are plenty. Also a little bit of searching and I found linux software too ( https://github.com/davidbuechi/UsbRelay ). Board also seems to have external +5V input possibility, which propably makes it possible for the relays to keep their state even if controlling computer is shut down - haven't tried it, though.
    Nice little USB controlled relay board for whatever you want to control.
