  • Really small!

    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......
  • Good 5V power supply for USB hub

    posted by radbasa

    The terminals are easily identifiable with large labels. Once set, this power supplies holds a steady voltage. The adjustment is fine enough for 0.05V adjustments, but that's overkill. The case is well-ventilated on two sides. The other three sides, the solid aluminum plates, serve as the IC heatsink. It doesn't get too hot, I can still handle it while under load.
    I haven't looked at its output through an oscilloscope. If I was going to use this for TTL circuits, I might check its output, but again, that's overkill.
    I ordered this to upgrade my 7-port USB hub from 1000mA to 3.8A. I am now running USB speakers, 2 DisplayLink USB-to-DVI adapters, 2 external hard drives, while charging an iPhone. It should be able to handle 2 more USB devices. Soon!
