Instructions for use
- Switching Display Parameters -- Under the normal interface, press SW to switch the down link display of the display screen, and the display content switches between current A, power W, capacity Ah, time h. Press and hold the SW button to switch the upstream display of the display. The display content switches between input voltage IN and output voltage OUT.
- Setting Output Voltage -- Press U/1 under the normal interface to enter the interface for setting voltage and constant current. You can see that a certain digit of the output voltage value is blinking, turn the rotary encoder left and right, and adjust it to large or small. Tap the rotary encoder to select which bit of the output voltage to set. After the setting is complete, press the U/1 button twice to return to the normal interface. Or the system automatically returns to the normal screen after stopping operations for 10 s.
- Set the constant current value (that is, the maximum current value allowed by the module) -- press the U/1 button under the normal interface to enter the interface for setting the voltage constant current. Then press the U/1 button to switch to set constant current value, you can see that a certain part of the constant current value is blinking, rotate the rotary encoder left and right, and adjust the major or small. Tap the rotary encoder to select which bit to set the constant current value. After the setting is complete, press the U/1 button to exit the setting voltage constant current interface and return to the normal interface. Or the system automatically returns to the normal screen after stopping operations for 10 s.
- Setting the Default Power ON/OFF State of the Module -- Press and hold down the U/1 button to enter the parameter setting screen. OPEN OFF or OPEN ON is displayed. OPEN Off indicates that the output is disabled by default during power-on, and OPEN ON indicates that the output is enabled by default during power-on. Long press the rotary encoder to switch between two states. After the Settings are complete, press and hold the U/1 button to return to the normal interface.
- Setting the Status and Threshold of Protection Parameters -- On the normal screen, hold down the U/1 key to enter the parameter setting screen. Press the SW button until the protection parameter you want to set appears. LUP- Undervoltage protection threshold; OUP - Overvoltage protection threshold; OCP - - Overcurrent protection threshold; OPP - - Overpower protection threshold; OAP - - Overcapacity protection threshold; OHP timeout protection threshold. OTP -- Overtemperature protection threshold. Tap the rotary encoder to select which bit of the protection parameter you want to set. Press and hold the rotary encoder to set the protection parameter on or off (only timeout protection and overcapacity protection can be set on/off, other protection parameters are enabled by default). . Rotate the encoder left and right to make the parameters smaller and larger. After the Settings are complete, press and hold the U/1 button to return to the normal interface.
- Calibrating Voltage and current -- Hold down the U/1 button to enter the parameter setting screen. Press the SW button until the parameter screen with CAL appears. The one with CAL+IN+V symbol is the calibration input voltage interface; The one with CAL+OUT+V symbol is the calibration output voltage interface; The CAL+OUT+A symbol is the calibration output current interface. The parameter size can be adjusted by rotating the encoder left and right. When the adjustment is complete, press and hold the rotary encoder to confirm the adjustment is complete. At this time, the parameter value is no longer blinking. Press and hold the U/1 key to return to the normal screen.

Using this to lower the voltage on a solar light i use nightly, and i am blown away how much better this is than some pack of bare bucks (having to solder on and deal with heat issues) chips.

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.

It doesn't have a main power switch. Sur it cuts the output power, sure But the display stays on draining ur battery so make plans in ur design to put a on/off switch before this unit. Its no biggy but its just one more thing u must add to the face of ur design possibly (as in my case) more precious space. I think that's weird /funny 😄. Sure its easy to slap one in a design but if the company describes it as having a on/off switch than it should have a on/off switch, that is what it should do! But this doesn't. It's got all these limiters in this program but it can't turn itself off. Im sorry I think its ridiculously funny 😄.Other then this I like it. It took me a good 1/2 hour learning all the functions (some are totally useless to me) BUT/and but! U can't change from C° to F° ok thats another flaw. Wthell u have English on the Display, 50% of us use F°. Funny funny funny 😄

I got a pan tilt security camera and the supplied power block didn't provide enough current so the camera would disconnect when moving the camera. I used an old 16vdc power supply to power the buck boost converter turned the voltage output to 6vdc and current limited to 3amps. Completely solved brown out problem.This little unit makes an awesome adjustable power supply for all your little projects too for the price.I have been running this unit 24/7 for 2 years and it is still working great. I plan on getting one or two more because they are an awesome way to power all of your DC electronics and to even get around batteries when the time calls for it.

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.

I thought this was a issue with the first one, so I returned it, and got another one, but it is clearly a issue with all of them.The unit does not read the stored value for the limited current between jobs. Has to be set every time. For example I am charging battery's with it, and if I set the current for 1.000 for 1 AMP, the display shows it running over 2 amps, once I start it.The same happens if I unplug it, plug it back in, press start or stop, with or with out a load on it at start up time. Once the load is added to it you get the same wrong amps. If the load is already there (in my case battery), same wrong amps.Only when I change the value while it is running, will it display the correct amps, example running at 2 amps, suppose to be 1 amp, if you set it to something like 1.001(while it is running), then back to 1.000, (again while its running), it then outputs the correct amps to the display, and the constant current light turns on.If I stop the job by pressing the nob on the right, then start the job again, by pressing the nob on the right, its back to over 2 amps, unless I set it while its running again. Just like I described above.This is frustrating, and very sad, because this thing checked every other box I needed, but I will be running eventually 10 of them and that is to many buttons to press to get it going correct.I believe this is a bug in the firmware, because if they wanted you to adjust every time, why would it save the voltage? I mean read the correct voltage... Whatever, I am sure you see where I am coming from.If you want a unit that you have to play with, and set every time, then this is a unit for you. It does charge the battery correctly btw, but you have to watch it, and make sure it is doing the correct amps, and so far every time I have to reset, I mean change the amps to something else, then change back, while its running for it to do the correct job.

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.
