  • Exactly what I wanted

    posted by mythic1

    -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.
  • 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....
  • Small and stable!

    posted by jackorobot

    Small form factor.Very stable output.Easy to see LEDs that show if it is in constant current or voltage mode.Very accurate potentiometer.Good use of heatsinks, does not get too hot.The PCB is very well labeled, so you know what everything means.
    Very nice product, very easy to implement in a project.I have used it in combination with a 24V, 3A power supply, and it works like a charm. It provides power for various projects, and is a lot cheaper than a complete lab supply.
    Good for people who know what to do with this.
  • Very good regulator

    posted by Bunny1

    Simple and robust, very usefull. You can change trimpot by fixed resistor, there are pads to do it, and it turns into a fixed voltage regulator. Overcurrent protection. Voltage adjustment is very precise.
    Small and simple, easy to fix, possible use in many experiments and prototypes. I saw some other regulators based in LM2596 more cheap, but using bobin wih low inductance, let to experience in future.
    If you need a regulator for experiments or low production electronics, use it.
