dc to dc converter Customers Reviews

  • Excellent product

    posted by intemann

    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 .
  • Exactly what I wanted

    -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.
  • Useful step up, but not step down

    WEll constructed with no signs of shipment damage. Came in EMF protected sleeve. Good fine grain control of voltage adjustment allowing .1V with good accuracy. 12.2V input gave a maximum of 37.8V output at maximum adj. 10.8V output at minimum adjustment (that's the brass screw on the blue box) Not carried out current load test yet. Probably very useful for boosting LED/ charge circuits requiring more than 12V
    Somewhat surprised this did not give lower voltage than 10.8 on minimum output (12.2V in) However I wanted a boost V output so this module was perfect
    As boost output this board is excellent. Good fine grain voltage control for V-out setting. Slightly too expensive compared with the other board http://www.dx.com/p/mini-dc-dc-voltage-stabilizer-regulator-module-red-126106 which is NOT a boost voltage, but reduces well to 1.V

    Native design. The 68uH closed core inductor. True Low ESR, high RMS in/out capacitors.
    There is even no place for feedforward capacitor on so large board. Feedforward capacitor 33nF-220pF you must choose yourself depend on Output Voltage and solder it directly at the variable resistor manually (see datasheet LM2596). It should be better if the board has additional soldering pins specially for feedforward capacitor package 0805 or 1206. Some other low price DC-DC converters provide less quality inductor, lower value capacitors and narrow PCB tracks.
    Work's well. Let's use it!
  • 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....
