If your power supply has a trim pot to it then you can usually trim it up 10% to around 13.2V. This might allow you to get to the 12V. **Q: can this provide 500 mV outpt to test gas valve ?** A: Yes, set the output to 0.5 volts. **Q: Is this cc cv ? thanks!** A: To those confused by some of the answers here: CV/CC or constant voltage/Constant current regulation means voltage output is regulated at the set value for loads less than the set current limit and regulates current for loads greater than the set current limit by lowering the output voltage proportional to the load resistance. E=IR **Q: I have a battery power bank of 24v of which each battery is 12v 210ah connected in series to achive 24v. canthis supply output12v,1.5a? a** A: Dear sir, About your issue, we have asked our supporters. The product could supply output 12v 1.5A. So you can try it. If you have any issued, please feel free to let us know and we will try our best to solve it.

I am always working on electronics project so I ordered a second one around 3 months ago, it worked well for a couple months but then started to turn off randomly. I contacted UCTRONICS customer service about the issue and after seeing the problem they sent a replacement right away. The replacement works just as well as the one that I've had for over a year now.The power supply is great for testing, or for a project that needs manual changes of voltage every so often. If you have an electronic project that needs a consistent voltage all the time I suggest purchasing a general voltage regulator preset to the specifications you need which won't cost as much or be as big, but this product could always be used for that purpose as well. I use it for testing all new parts or sensors I get which usually operate at different voltages and current, so if you have any plan for that type of use I highly recommend. ### ⭐⭐⭐⭐⭐ Works great! *by on Reviewed in the United States July 13, 2022* I connected the boost converter (https://www.amazon.com/dp/B07T137H2Y) to this adjustable power supply module (https://www.amazon.com/dp/B01LWXAC5E) on the output. And I have a Volt/Ammeter (https://www.amazon.com/dp/B072BY4XZ7) on the input. All supplied by a 12V marine deep-cycle battery on the input. It was giving me 24v out from the start. I need 48v so I dialed this boot converter up to 50v, and fine-tune the output using the adjustable module. Been running for 2 weeks 24/7 and it's driving 7watts during the day and 15watts at night. No troubles so far! The output is powering a PoE ethernet hub that as a pair of PoE cameras (https://www.amazon.com/dp/B07V1WKRBB). It's all working really well! Once I'm done will the cameras, this will be my workbench power supply. ### ⭐⭐⭐⭐⭐ Great Quality for the Price, Must Have for Raspberry Pi Projects *by on Reviewed in the United States February 6, 2018* Using this to regulate the power for my Raspberry Pi 3 stack with 2 Pi Plates and a 7" LCD. I'm using a 19.5V DC 3.5A laptop power brick to supply this regulator and the output is strong and constant. Because Pi projects mainly need 5V DC, voltage drop is a problem on my projects. Stock 5V power adapters just don't cut it for most of my projects. With this regulator I am able to adjust the output voltage precisely by 0.01V increments and get the 5V just right at the Pi. No more low voltage warnings!Pros:Precisely adjustable, reliable accuracy, clean display layout, color LCD makes it easy to quickly see the values I'm looking for, love having an on/off button, when off it still displays input voltage, shows current and power draw, can set memory for quick recall of different settings, does not get hot even in periods of extended use (days), very small unit for what it does.Cons:The one thing I don't like is that it is intended to be panel mounted and my applications don't give me that option normally. Not a problem, but would be great to include a small enclosure it can fit into.The adjustment knob is a bit big for such a small unit, but bigger may be better for those with bigger fingers.Improvement:It would be amazing if one of these regulators would be manufactured to fit in as a component with the Pi stack... I'd buy at least 4 more!! ## Frequently Bought Together - UCTRONICS Numerical Control DC 6-55V to 0-50V 5A Step Down Stabilized Power Supply Constant Voltage Current Buck Power Converter Power Supply Adjustable Module - Hilitchi 40 Pcs Binding Posts Terminals 4mm Banana Plug Socket (20pcs) + Red and Black Gold Plated 4mm Banana Plugs(20pcs) for Arduino - HiLetgo 250W DC-DC Module 10-40V to 10-50V 6A Adjustable Step-Up Power Supply Module Constant Voltage Constant Current Power Converter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/35596117-uctronics-numerical-control-dc-6-55v-to-0-50v-5a](https://www.desertcart.co.uk/products/35596117-uctronics-numerical-control-dc-6-55v-to-0-50v-5a) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-29*
