Works great so far. Still learning how to use the adjustments on it. Plugged it into 12V DC and was able to adjust from almost 0V to 22V. Will try to go higher but not needed for me. It is a very fine adjustment so get your wrist and patience ready if you need to go higher volts with it.

Every once in a while you purchase something that really impresses you, and this time it is this little device. It has a bunch of features and performs flawlessly. I connected it to an old 12V 5 A PS I had saved from a malfunctioning printer.In the past few days I have used it to charge two different batteries, one NiMH and one LiFePO4, run a low voltage, fairly high current motor and run a digital electronic development system.Particularly useful is the boost/buck ability as well as the ability to verify the input voltage and current.Excellent product.

SO I have had this for about two weeks. The setup was very simple Connect your input in my case a 24 Volt 100 amp Battery, and then your output in my case I am powering a computer monitor that requires 19 Volts. Drum roll please..... The monitor turned on and worked. The first thing I noticed was the meter says .780 of a amp when the back of the monitor says 1.5 amp draw, however that could be the manufacturer telling the maximum draw instead of the actual amount it was not really clear. Over the last two however the amount the monitor is drawing has decreased according to this meter. Since the brightness of the monitor has not decreased, I am going to say that the meter is not reading the amperage correctly as of today the meter is say .30 of a amp draw opposed to the draw the first day of .780 of a amp. and again, this reading has steadily decreased over the last two weeks. Since I am not preforming any scientific studies how much the meter reads really does not matter, as long as it keeps the monitor powered.

I bought a couple of similar modules to test for amateur radio application. The first thing I noted was that the heat sink was loose. It didn’t press against the components it should cool. It was just a mechanical problem the single screw holding it in place was cross threaded during assembly. To fix it I had to cut away two blobs of heat glue which was used to hold the top board in place. The top board with the heat sink and power components could then be easily removed. After reseating the screw and heat sink I had hope that this was just the only problem, put it back together and start testing it. I applied 12V from my bench power supply at the inputs and connected an electronic load at the output. The output was set for 13.8V and I left the current limit at the default of 5A. Starting up with no load it was providing 13.8V exactly. But when I increased the current draw at the load the voltage start dropping around 1.5A draw. It did not go to constant current, it just folded back. I did go through all the settings but no matter what, I was not able to draw more current. I guess there was more wrong than just the loose heat sink. I also bought a similar Buck/Boost converter which was a bit more expensive but featured a color display and a fan and worked to my satisfaction in the same setup.

Tengo unas instalaciones de camaras de videovigilancia, en las cuales mi fuente de poder original suministra entre 11.5V-15Vdc a 2 amp. Este regulador lo puse a la entrada de voltaje de la camara, para suministrarle voltaje 12Vdc a 1amp, regulado perfectamente y soportando cualquier variacion de entrada.Es posible utilizar este equipo para suministrar mayor voltaje del que genera tu fuente de poder, siempre y cuando el amperaje de consumo sean menor al total generado por tu fuente de poder. Es decir, si necesitas 20Vdc a 1amp, y tu euipo genera 12Vdc a 4amp, entonces podras utilizarlo sin problema! Pero si tu equipo genera 12Vdc a 1amp, ni de chiste podras usarlo, ya que no hay suficiente para incrementar el voltaje.El equipo tiene muchas otras funciones programables y es muy amigable. Si necesitas conocimientos de electronica y electricidad para usarlo, no es para principiantes.

Sólo agreguen una fuente de alimentación y listo, puedes regular el voltaje y amperaje.
