5v switching power supply Customers Reviews

  • A cheap and good power supply.

    posted by nicolasantoci

    It is an economy and good source power , for electronic projects with microcontrollers. The value of 5V can be adjusted by the potentiometer.It is very interesting to do projects.It has a hole in the sheet to insert a screwdriver and calibrate tension without removing the aluminum housing.
    Maybe a switch could it have but I don't think it will be a problem.
    It's a good power supply and you will not be disappointed. It is a very good buy.
  • 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 small power source.

    Small compact power supply which delivers a rock solid, stable, 5V. There is a pot to fine-adjust the output voltage. The case has enough perforated holes to get it ventilated. The power transistors are mounted to solid aluminium heatsink which is part of the housing.Good powersupply once you have checked it.
    You have to check the pcb on almost short circuit wires from the components.Also apply heat transfer compound yourself
    Cheap. Does the job once checked. Get one.
