    Excellent power supply, no problems to build. The PCB has a good parts print, no problem to place the right part. I have ordered the "Heat Sink + Cooling Fan Kit" ( Product ID 1067407 ), the case "Electronic Plastic Shell Case Desk( Product ID 1035473 ), "Nickel Plated Binding Post" ( Product ID 953213 ), "Plastic For Rotary Taper Knob" ( Product ID 953378 ), "3 in 1 Power Supply Socket" ( Product ID 1051419 ) and "0-33.00V 0-1A-3A Four Bit Variable Precision Voltage Current Meter" ( Product ID 1061330 ). The later because I wanted a more precise display for the real current specially in the low current range. You can see, the voltage is relative precise, the current from the internal display is a little bit higher than the real current. The only thing I could not buy from Banggod was the transformer. This power supply is a great enhancement for my electronic workplace !

    Initially I bought just the kit, but was struggling to find a heatsink for it, then the Bangood one appeared so I ordered that, along with the case suggested in the pictures. To make the front neater I mounted the LCD assembly using countersunk bolts, and laser printed a front panel, laminated it, and glued that to the front panel. The extra thickness meant it wouldn't fit in the slots, so I milled the back a little thinner using a Dremel mounted in a drill stand. I ordered front terminals from Bangood, along with an IEC socket/switch for the rear. This left me requiring a transformer, which again I struggled to find - eventually I ordered a 24V SMPSU (http://www.banggood.com/4A-To-6A-24V-Switching-Power-Supply-Board-AC-DC-Power-Module-p-969204.html) from Bangood, and modified it for 30V by adding a 5.6K resistor in series with the existing 20K one. The output of this PSU is soldered directly to the reservoir capacitor on the board, bypassing the rectifiers.

    Good components and PCBs. Clear instructions. Easy to solder. Very easy to setup and use. I bought two kits to build a modular dual voltage power supply [postive output/common reference/negative output]. I also bought the original heat sink and fan (Product ID 1067404), red and black terminal banana plug sockets (Product ID 1046083) and plastic knobs (Product ID 983613), all sold by Banggood. I added a toroidal transformer, a red rocker switch and a black plastic shell to complete this project. Finally, the twin power supplies are ready!

    Finally I have adjustable power supply. :) It is super easy to build, cheap and works as it should.

    This kit is a relatively easy easy build and the PCB and all components seem to be of good quality. Setup and calibration is simple and the completed power supply is a sturdy addition to your test bench. Make sure you also buy the case and heatsink & fan when buying this kit. Also, no transformer is provided so a 50+VA 24V (or 12v-0-12v) should be sourced separately. For a finishing touch, buy a couple of push-on knobs for the voltage and current selection controls.

    The DIY kit came on time and was a lot of fun to build. It works great and did not have any issues. Only needed to adjust the 10K pot on the control board to get the display to show its information when I first powered it up the display was blank, and then adjust the 1K volt trimpot on the main board to get the output voltage to match reading on the display. I am very happy with the finished project.

    Produkt als Beschreibung. Zusammengebaut das Diy-Kit und installiert auch das Kühl-Kit für den Leistungstransistor. Funktionstest war ok funktioniert wie erwartet. Feinabstimmung der Ausgangsspannung auf das Display passen. Empfehlen.

    I bought this kit as a small time filling project. I didn't need another PSU but I was tempted by the digital control side of things instead of the usual analogue type. The kit as supplied took an hour to build, no real challenge so is ideal for beginners in that respect but it is useless to a novice who has no spares or 'junk box' to pull the needed parts from. The hardest parts to source would be the heatsink and the case. I have read reviews here saying that the fan is hard to get hold of but the first one i pulled from my junk pile was 24v, made by Papst. I never used it in the end as I used a heatsink with a reasonable surface area. If you need a fan, the any 12v fan will do, just add in a resistor to give you the required voltage drop. The other thing that would be hard for a novice to source would be a suitable transformer. Again, the first one I pulled out of my junk box was a 3-5A one from an old cb psu. I did find a couple of torroidal transformers but they were too small current wise. I had a spare plastic instrument case so adapted it to fit all the boards and extended cables when I needed to. The fitting and cutting of the case took far longer than the electronics part. After I had built it, first switch on showed just a plain display but when I adjusted the contrast it worked fine. I then calibrated it against my fluke 77 and my Avo 8 Meters. a small adjustment on the main board pot and it matched the displayed voltage to the actual voltage on the external meter. There is a slight discrepance at the extreme ends of the range but as I plan to be usin this closer to the bottom end voltage wise I settled on making it accurate at 7.5v and that kept it within 100mV of the actual output from 1v up to 15v How would I improve the kit? Well, making it complete would be a start. To finish it you will need:- Transformer Heatsink Fan Case Mains Socket Power switch Mains cable Fuse holder Fuse Control knobs Output terminals Screws/bolts. Overall, it was a fun easy build, but as I worked as an electronics engineer for many years I may be overstating its simplicity, especially for those who are just starting in electronics. The quality of the supplied components is good, its just that you need so much more to finish it that I have to mark it down on overall score. To buy all the missing parts will easily double the kit price but it would be worth it if Banggood gave you the option.

    Just finished assembling this little programmable power supply. For the price, this is just great! No missing parts in the KIT, nice quality control for a change... Worked perfectly on first powering up! Takes about 2 hours to complete - Must be familiar with parts numbering, coding and identifying but fairly easy to figure out. One caveat, make sure you soldered the socket for the 5 fire connector between the screen and the power board. With the LCD board, the socket must go on the back of the board otherwise the LCD screen won't fit...! Check orientation as well, +5volt must go to +5 volts, etc. Great kit in general - I am ordering another one right away for a dual + and - power supply!
