Great little adjustable power supply. Only reason I gave it 4 stars is because of the heat. The fan on this little thing can’t keep it cool enough to run at 5 amps at 24v. I used hot glue and added a bigger fan. This is the second one I have gotten because I love these little thing! Great for fans or lights or troubleshooting stuff.

Works as described, but if you need more voltage get one with more voltage output.

I bought this unit as an upgrade from a cheaper 4amp unit that did not work as I had hoped. So far, this unit is everything I had hoped it would be, and more.-----------------Pros:On-off button controls the output, not the display. This is absolutely a plus, because it means that one can adjust the desired voltage and current settings before turning on power to the output. (One can also adjust settings while the output it on, but this switch adds flexibility.)Bright, color display shows a wealth of information in a single screen.Built-in fan to keep components cool.Easy to mount the unit - just cut (or 3d print) a rectangular opening of approximately 75 x 39mm and pop it in---------------Cons:The interface is a bit complicated / tedious, though it gets easier to navigate with practice. Other than the on/off button mentioned above, all input is handled through a single rotary/push-button knob.The included manual (and the one available on-line) does not entirely match the unit, especially for the last "preferences" screen - the unit I received seems to have more options than what the manual shows, and I have not figured out what some of them are.This unit is bulkier than the 4-amp unit I started with; with the latter, I was able to build my DIY bench power supply entirely within the case of a surplus PC power supply. To accommodate this unit, I had to create a 3d printed "extension" to the case to allow more room.-----------------The pros far outweigh the cons, at least for my purposes. I have not had the unit long enough to know if it will remain reliable over time, but so far it has given me exactly what I had hoped for in a cheap DIY bench power supply.

This is such a simple-to-use perfect device for building your own variable power supply!Just grab an old power 'brick' (because I know you have some) ... and put it into an enclosure with some binding posts, and there you have it!The 'power brick' makes it electrically safe for your country, (because if you have one - it's already certified for your country) and the DC output is 'dial-in' adjustable. How cool is that?!?!

Very nice CC/CV buck converter. Works as it should, accurate display.Interface is easy to use, everything except storing settings to presets is self explanatory (still haven't figured it out - didn't check the manual yet though)There is no diode for reverse polarity protection, so careful when charging batteries. A diode in the power supply would always make the current/voltage readings less accurate. Not by a huge amount, but enough to be an annoyance in some cases, so best it's not included. To protect the supply, you can always add one after the output and increase the charge voltage set, by the diode's dropout voltage.

Disappointed to find out the 250w and 750w LCD display buck regulators are not from the same series and have slightly different operation modes, so if used in the same location, it would make for user awkwardness.The 750w unit is excellent, good easy to use controls that make sense for quick and easy access to the voltage and current settings, only thing better would be 2 encoder knobs dedicated to each voltage and current. It’s only real downside is the lack of fine adjustment for current limiting, which should be complemented by the 250w unit’s finer adjustment.The 250w unit is a lower series model (one exists that matches the 750w unit’s controls but with the 250w unit’s fine adjustment) that has much less intuitive controls. It does operate very well but in order to manually change either V or A you must press the SET key then press the encoder wheel button to move the cursor to the desired digit you want to change. That’s 7 times you press the encoder after pressing set every time you want to fine adjust current! Terrible for a bench top variable power supply, which was my plan.Considering these two units are sold under the same listing as different “sizes” it is truly a disappointment to pay good money to have the unit delivered quickly from Amazon only to find out I must now order the correct unit directly from eBay/China in order to complete my project.For people wanting to find the correct matching units, the 750w (generic) model appears to be DPS5015 and the (not listed) matching 250w model is DPS5005 to search for if you need them to operate the same. The 250w model sold here is more similar to the generic models listed as DP50V5A although not exactly identical either.

The unit works like a charm, and does not seem to budge under load. I did not read the instructions, but it was fairly self explanatory. The knob is "pushable", several times, to allow for a finer degree of voltage control each time. Sweet, very sweet. Good thoughts put into the product, including a removable connector. Aesthetics is what it is, depending on the taste of each person.

This device fits a need I have for a variable power supply. I have a number of fixed output power supplies that I used with my amateur radio equipment but needed a variable supply. First the physical format was just what I was looking for. It is small (4.2 x 2.7 x 2.4 inches) yet the display is large enough to easily read. The case has tabs on the side so that it can be mounted in a box or cabinet without having to use any mounting hardware. The connector are properly located so that connecting it up is very easy. It has a lot of options for setting the voltage output and current. Setting these parameters is quite easy and can be done quickly. There is a button to turn the output of this device ON or OFF. The input can vary from 6-55 Vdc and output of 0-50 Vdc. You can read the other parameters in the ad above. When the dc to dc converter is used to charge a battery or to be capacitive load, it must be in series with a diode, or the module will be damaged. A power diode is included in the kit for this purpose. Below are some of the measurements I recorded.Input voltage = 18.8 VdcLoad was a 10 ohm 1% 5 watt resistorTest 1:Output set to 9.10 Vdc at 1.0 AmpsMeasured output: 9.07 Vdc at 0.887 Amps on device display and 9.01 Vdc on separate meterTest 2:Output set to 5.00 Vdc at 1.0 AmpsMeasured output: 4.99 Vdc at 0.491 Amps on device display and 4.94 Vdc on separate meterTest 3:Output set to 2.50 Vdc at 1.0 AmpsMeasured output: 2.49 Vdc at 0.243 Amps on device display and 2.48 Vdc on separate meterTest 4:Output set to 8.00 Vdc at 0.40 Amps (for contant current)Measured output: 4.07 Vdc at 0.40 Amps on device display and 4.00 Vdc on separate meterTest 5:Output set to 8.00 Vdc at 0.50 Amps (for contant current)Measured output: 5.08 Vdc at 0.50 Amps on device display and 5.01 Vdc on separate meterTest 6:Output set to 8.00 Vdc at 1.0 Amps (for contant current)Measured output: 7.98 Vdc at 0.78 Amps on device display and 7.96 Vdc on separate meterNote that the voltage and current can be adjusted to give the desired outputs more accurately.I was very pleased with its performance.
