    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
  • 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.
  • Nice stepdown DC converter

    A small PC wich has the advantage to set fixed voltages wich become handy in Ohm-resistant situation if you want to get a good controll over the current.The dipswitch works good if you know how to handle it.
    This last point can be solved by giving a firm overvoltage (within the range of the converter)Because the energyconversion is high efficient, these units are much better than the 78XX (or 79XX)wich converts overvoltage only in thermal enery (they become hot )These kind of converters do normaly not use extra cooling (convection is enough) unless the differece beween input and output volage is big and/or the current, drawn from the converter reacht to the maximum, it is no good idea to rely on the thermal/current protection, other parts or instability can be damaged, capacators (elco's) have a much shorter shelflife when they heat up, their value changes above the limits and they can ruin anythingin line of it....
    Not the cheapest and not the smallest DX converter but certainly one of the most reliable....

    - It has good stabilization of the output voltage. When i have supplied it with 12V the output stayed constantly at 4.99 - 5.03 volts regardless of the output current which was between 0.5A to a maximum of 2 Amps
    - A small switch would be a good addition to it when using in the car, or at least connecting it to a switched plus is a good idea to prevent it from running idle and flattening the battery.
    Very good DC power supply, with stable voltage. The price could be better though.

    Well priced , good looking unit . Easy to fit into Trucks , Diggers and larger vehicles .
    Good construction , mounting can be done with a cable tie . Mounting holes too close to unit to be able to drill .
    Needs fusing on 24 volts input and 12 volts output I think that the unit should come with 10 amp fuses and holders . Cost would be more but worth doing and paying for .
