  • Does the job. Cheap & customizable

    Involvement Level: Expert (understands the inner workings)

    Pros: Pretty cheap. Wide voltage range. Useful for constructions when you need to get several voltage levels from battery of other lager level.

    Cons: No reverse input voltage protection. I 've destroyed one module in a few seconds just by wiring it incorrectly by mistake. Easy workaround is to solder protective diode in parallel.

    Other: Nice thing. I will perform the test with other voltages&currents I require in my constructions, and then probably buy more of them. Definetely worth the money spent.

    Involvement Level: Expert (understands the inner workings)

    Pros: Very small and easy to fit. Nicely built. Clearly labeled connections. Works as advertized.

    Cons: Could have been shipped with some power connectors installed which would make life easier. Voltage adjuster needs many turns to start acting up for different input voltages.

    Other: Very handy little product. I will definately buy again if needed.

    Involvement Level: Expert (understands the inner workings)

    Pros: It does what it;s supposed to be doing and it is cheap.

    Cons: I used it to feed a 24 channel servo driver with 5V. The original source was 18V 6A, and the average current consumption on the driver peaked at ~1.5A during the testing of some servos. The problem is that after 30-40 min the whole contraption got too hot and the unit smoked. This wouldn't have been a problem except that once the transformer blew, it leaked pure input voltage on the output lines, thus feeding all my servos with 18V. WARNING! Long story short, it cost me 24 servos.

    Other: It's not a bad unit, but use it only if you're sure of what you are doing. Be careful to compute you current consumption, and add a heat sink.

  • good quality converter

    posted by Haitze on 15:20:23 G2T 10/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Good quality converter, high quality Pcb material with red coating and good solder quality. smal size PCB low energy loss. The default outputvoltage = 12V. You can adjust the voltage by turning the small screw on the PCB.

    Cons: the divice cannot deliver more than 1 Amp at max. You need to solder the wires to the board, no connectors (If you have a good solder iron than that is not a real Con.)

    Other: A good small and efficient step down converter for anyone who needs one.

  • Nice little power conversion modules

    posted by Delirioux on 07:35:25 G1T 14/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This module was exactly what I was looking for. In my rc planes I needed to power a little camera, so I used this device to step down the voltage. It is simple to use, easy to adjust voltage. Since I do not use it to draw a lot of current, in my case, the unit doesn't get hot. I would recommend this unit to anyone if your current requirements aren't too high.

    Cons: No cons for this product

    Other: Small, light easy to use module to fit to your power needs in your projects.

  • Cheap useful DC-DC for DIY

    posted by NiTr0 on 12:52:13 G9T 21/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Cheap, small, enough powerful DC-DC convertor that is suitable for DIY projects. You can achieve up to 2A continuous current with additional heatsink.

    Cons: Without heatsink it becomes too hot at current near 1A; coil at 2A current is 10-15C hotter than other board/heatsink (it'll be good to use coil with lower active resistance)

    Other: Cheap and useful device, without big cons at it's price. It's cheaper than single IC when you buy 10+ pcs.

  • very small step dowp PC

    posted by lasermanathome on 14:11:54 G8T 07/08/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very small unit wich makes every voltage below the input possible, with high efficiency and a good current. Produces almost no heat and is stable, within the specs of the manufacturer.

    Cons: A pot for regulate the currentlimiter would be nice. In that case this unit becomes an universal driver for almost every electric low voltage system. But again, the pice is unbeatable for what this pc is capable of.

    Other: Do I need to write more?!!
