Aclorol 5V 20A 100W Switching Power Supply 110V / 220V AC to DC 5V 20amp Universal Power Transformer Driver Converter Adaptor for WS2812B WS2813 LED Strip Pixel Lights CCTV Camera Security System

I bought this to power a small Bluetooth 2.1 amp. When it came in the package, there were no instructions, but it's not hard to figure out. There are three V+ (positive), three V- (negative), a ground, a Neutral, and a Line screw. I took apart an old computer power cord and used that as my power cord. I then used the fins on the right side to zip tie the cord to the box. That way, I'm not relying on the screws if there is any tension on the cord.I connected a multi-meter to the outputs and played with the adjustment screw. It went all the way up to 40V, but then I set it back down to exactly 36 volts for what I needed it for. But it's good that it can go up higher than that.It does have a fan that will turn on if it needs to, but it hasn't needed to yet.Overall, this is a nice power supply with some pretty decent capacitors. When you pull the power, you will notice that it takes a long time for the power LED to go out. Almost 30 seconds total! That's a good thing because having good capacitors means that the power output will be steady.I would definitely buy this again, if I needed another one. It's very well made.

Bought this for some outdoor LED strip lights, and it's working great for the last two months.

Used this in an LED pixel tape setup with a breadboard inside of a mini golf hole. That thing was powered on 24/7 for weeks and didn’t fail once. Excited to pull it out on a couple months to use again.

Very good product gets the job done

Very good PS 5V. Keep voltage very steady on consume variation. Has a dial that will adjust the voltage in the range of max. 15%. Do not overheat and very stabile. Great PS for 5V projects.

The media could not be loaded. This power is replacing a 50A Meanwell PSU. It has the 120/240 selector switch (manual switch). The bolt/screw patterns lined up with the Meanwell perfectly. Super simple swap and it powered up immediately. This model was thicker than the LRS 350-5 it replaced, and the fan was also thermostatically controlled. If it doesn't spin when powered on, it will under a load. I can update this review after 1 year to share it's reliablilty.

Powering two light strips and with both at max, drawing 18 amps, the voltage at the power supply was 5.02 volts. Works great!

I ordered the 5V 40A version and so far, I'm pleased with it. It's got good shielding and puts out plenty of amperes, even a 5 meter 300 led strip could be lit up without a problem. One thing I do wish for was a more accessible trim potentiometer since its tucked away under the shield and slightly behind the screw terminal.Other than that its output voltage should be measured before connecting anything to it, as mine output 5.14V without adjusting the trim pot.
