• UCTRONICS Variable Bench Power Supply - Buck Converter DC 6-55V to 0-50V 5A Precision Digital Adjustable Step Down - Constant Voltage and Current, 10 Preset Settings Switchable: This power supply combines digital control with analog integration. Its output range: Voltage is 0-50.00V, step by 0.01V; Current is 0-5.000A, step by 0.001A
  • This step down voltage regulator can store M0-M9 10 groups preset value when power-down. Keep pressing M1 or M2 more than 2s, the corresponding data group will be extracted and displayed on the right of the screen
  • The 1.44 in colorful LCD monitor can display the preset voltage, input voltage, output voltage, the preset current, output current, output power at the same time. On the output state remind area, you can monitor that the key is locked or not, output is normal or not, the state of constant voltage and constant current, the current data set prompt and output opens or not
  • There are four button-"M1", "M2", "SET" and "ON/OFF", and a coding potentiometer. Can be used for to set the output voltage and output current on the main display interface, set the data on the data setting interface, set the protection value, adjust the brightness of screen, extract Shortcut storage data group M1 or M2, etc.
  • Note: When the output of this step down voltage regulator is used for charging a battery or connect a capacitive load, there must be a diode in series with the output-anode, otherwise the regulator will be damaged

I have this hooked up to an old laptop power brick, and it does admirably as a simple and inexpensive power supply for powering simple setups. I need a mix of 3.3v, 5v, and 12v, so this works great off a 20v input. I'm thinking about bringing one of these along next time I go camping so I can charge USB devices (5v) and run car accessories (12v) off my (36v) ebike battery.

Works perfectly. Very clever design putting a constant voltage/constant current DC converter in a snap-in panel meter complete with metering. All functions work as advertised. Calibration is pretty close. But, you need forced-air cooling from a fan; all the time. The switched-mode controller runs hot. Not a design problem, because that's how the technology works. Put a fan on it or don't complain when it up-and-dies on ya' ! The outfit that claims responsibility for this has a website with details on their product line, including repair procedures; Way to go "RD Tech".

What a great product! I was able to build a dual-channel power supply with this thing and I've been using it regularly for the past month to debug some prototype PCBs I've developed for my work. Amazingly enough, I was able to find everything I needed from Amazon: Chassis, with vents: uxcell 9.8" x 7.5" x 4.3" Blue Metal Enclosure Project Case DIY Junction Box AC/DC power supply: Aiposen 110V/220V AC to DC 24V 8A 200W Switch Power Supply Driver,Power Transformer for CCTV camera/ Security System/ LED Strip Light/Radio/Computer Project( 24V 8A) Power socket: URBEST Inlet Module Plug 5A Fuse Switch Male Power Socket 10A 250V 3 Pin IEC320 C14 Banana jacks: Wiwaplex 10Pcs Gold plated Insulated Terminal Binding Post Power Amplifier Dual 2-way Banana Plug Jack For my purposes, I don't plan on using it to supply more than 16V/2A per channel simultaneously. It's nice having different memory settings so I can easily dial up custom configurations depending on the PCB I am debugging.

Great for my home built bench power supply. I used an old printer power supply to feed the thing 32v and I am able to set it to anything under about 30v reliably. I love that it gives you load readings and has a "safety cut-off" feature that will cut power if it goes above a set load to prevent overloading your circuit. Everything seems to be pretty accurate as measured by my voltmeter.

At least! This little ( not expensive either) regulated Power Supply allows me to have a spare on hand. I use them in my jewelry plating tanks. I drive three units with my old auto battery charger (It's like me to old to be smart). It handles all three with ease. Because the current used in electro-plating baths is so small The current is well regulated. Which prevents burning and over/under plating. I plan to keep a spare on hand and now I can afford to.

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!!

I built a power supply that is variable out of an old power supply from the 70's. This thing is wonderful for the price because it's capable of working off of a battery as well. So if and when I am done making my off grid solar powered home as efficient as possible, I can still use this from a 24 volt DC outlet. It limits current, sets voltage, displays everything I need it to so far. The menu is not that hard but maybe not as convenient as a standard variable power supply for electronics testing.

It is everything I wanted and nothing I didn't. It was cheap so I was worried about the quality but that is way above average. High quality parts and an excellent wire attachment section on the back. I was looking for a variable power supply, but now I'm just using a computer one and stepping down from 12v as all the voltages I work with are under 12v. Neat setup that I never considered and it's way smaller, I've even rigged it to go in the car for testing. Love it.

The part works amazingly. I ordered one of these modules around a year ago and it worked incredibly well. 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.
