  • Mobile power suppply

    posted by Koppen24

    Handy device, easily and accurately set. I use it in my car for media player. with 4 diodes I have the input voltage 2.5 volts lowered, then I could adjust the tension nicely at 12.5 volts. because a car when the engine is running 14.5 volts charging. The media player works well and without fault in sound or image
    the device is recommended for anyone with a laptop on the go with the car.
    Handy device for little money, certainly useful for a laptop because they are generally at a higher working voltage than 14.5 volts in a car.
  • Very good regulator

    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.
  • Small and stable!

    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.
  • Variable voltageboost from 12v to 35v.

    - Size, a very small package- Mount feets- Easy to equip - Very easy to use- Looks as good quality work- Very cheep
    I bought this to be able to variable boost voltage going to 12 non-pwm computer fans and to test if it can provide enough power to supply some smaller peltier elements. So far I have tested the voltage going smoothly from 12v to 35v, and a 3000 rpm scythe 120x38mm fan. My god a fan like that can eject some air when voltage goes up.
    Better than I expected. Looks a lot bigger on the picture on DX.com than it really is. I am very satisfied.
  • Nice for voltage regulation

    posted by waynedevereaux

    Great little device for regulating voltage. Especially when some electronics require 12 v constant and turn off below a given voltage. Small potentiometer to adjust the voltage.Boosts 7v up to 12v no problems. Great for monitors and cameras.Fast shipping was here in just over a week.
    A cheaper rate would be better
    Great device,id be lost without it!
