  • Good quality S/W PSU

    posted by platonas

    It is small and of good built quality. I tested it at 5V/2.1A and the voltage stabilization is very good, 0.5% as stated.
    I removed the fixed resistors that define the output voltage and installed a trimmer of 50K and a resistor of 1K8 in the place of the 15K that was on the board. The board had 47K and a 15K that define a 5v fixed output. With the 50K variable an a 1K8 fixed I have variable PSU now.
    I would buy some more for my projects. The price is good compared to the quality you get.

    -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.
  • Works for me

    Cheaper than building it myself here... Since where I live the components are not common.
    Could be cheaper, maybe?
    It is compact and exactly what I needed to have my internet router working on batteries in case of power shutdown!It even has a LED that I find useful to know if it is actually working and I didn't know it had it.Got it encased and mounted in 10 minutes. The other one I made myself took me more than a week since I had to build my own cooper coils, and a generic circuit board because nobody sells them here.
  • DC Voltage Regulator

    posted by NektariosSp

    Great piece. Quite useful. Not possible to build one, using ordinary 7805, cables and a USB socket. Works fine, but I have not tested it running to the current limits. Great for installation in cars, DIY projects and of course, for connecting any USB powered device.
    I have no other thoughts.
    Good to buy. Nothing special needed for installation.

    very stable and the current that provides is more than enough to power my raspberry pi. Absolutely does not heat up so I think it definitely has a good performance. the current and the voltage seem stable.I recommend it to all those who have to power a device to 5V, probably even in your car is a good substitute dell'accendi cigars as it has a higher return
    with 12 V input voltage does not heat at all
    is just what I wanted to not use a 7805 which dissipates a lot of heat.With a 7805 I put a heatsink but it was so hot you could not touch
