BTF-LIGHTING AC100-240V to DC5V60A Max300W Switching Power Supply Device Transformer Adapter Converter for LED Strip/String/LED Matrix,CCTV Camera,Security System,Radio,Cats

I purchased this BTF-LIGHTING 5V 30A power supply to run multiple LED strip installations, and it has performed exactly as expected—consistent, stable, and dependable. Excellent Power Output: The 30A capacity gives plenty of headroom for high-density LED strips and microcontroller projects. Voltage output stays steady even under heavier loads, which is crucial for preventing flicker or color shifting in 5V LEDs. Build Quality: The metal casing feels solid and well-ventilated. It doesn’t overheat, even during long operation, thanks to the built-in cooling design. The terminals are clearly labeled and secure, making wiring straightforward. Ease of Use: Setup was simple. The screw terminals hold wires firmly, and the input range (100–240V) makes it compatible almost anywhere. Once installed, the unit runs quietly and without any buzzing. Performance in Real Projects: I’ve used it to power addressable LED strips, a small Raspberry Pi setup, and some 5V accessories simultaneously. Everything ran smoothly with no drop in brightness or unexpected shutdowns. Things to Know: As with most open-frame power supplies, it’s best mounted in a safe, ventilated area or inside a project enclosure. Not something you want loose on a desk. Bottom Line: A strong, stable, high-capacity power supply that’s ideal for LED strip lighting, makers, and DIY electronics. It delivers clean power, stays cool, and is built to last. Highly recommended for anyone needing a reliable 5V power source.

Please do NOT use my photo as a reference, these pictures were taken when I was learning how to use it. It is a learning process to those who are not familiar with working with this kind of stuff, and you have to be very careful. Please do NOT work with these while it is plugged it please. I am very pleased with how these turned out! I bought two of them and I am joyful to know that my led strips work fantastically! It is very easy to screw down the wires, there is no need to put it together, you just screw down the wires and you are good to go! I would like to add that I really like how they come with an orange plastic flap that keeps the wires and the screws protected, it is an admirable safety measure that made me feel more at ease when I first started using them. I was terrified at first! 🤣 The labeling above the screws are also a good help identifying what each purpose of the screws are, like which one is for the positive wires, which one is for the the positive wires, so on and so forth. I still have some things to learn but this was a nice start and I would recommend this to anyone who is in need of a power supply like this!

used this to power a Christmas village. just put a diode on the output and adjusted the output to 4.5vdc.

Very good

The power supply works great and added it to a single ESP32 controller with WLED (v0.14.0) in a 5 multi-strip configuration (325 leds total). Everything works great now but had to troubleshoot to get it there. Having 2 output nodes, I originally split the power from the power supply with one going to the controller and the other to the LED strips. Running 1 strip was fine but when I reached 3 strips or higher, I would get random flicker on the last 1-2 strips. (Last being defined as the last segment in WLED). Everything was fine if 1 strip was powered at a time. I resolved this by only running power from 1 node pair from the power supply to both the ESP32 controller and the LED lights. Power being split between all 6 devices (controller + 5 strips) from the power supply. LED power did not go through the controller, only data. That resolved the flickering issue, and all 5 strips now work perfectly. I'm not an electrician and don't know the root cause other than assuming that a power fluctuation occurred that was enough to create interference.

Purchased 5V 150W version to drive WS2812 LED light strip. With only 180 LEDs = 60W max was seeing voltage drops to under 4V as LEDs go from dim to bright. After realizing the hidden switch was set to 220V and correctly setting to 110V it is now regulating the voltage fine. it's a little hard to tell where the switch is set without opening it but you can actually get to the switch with a small screwdriver poked through the holes in the case. However this is the ventilated, non-fan version. Continuing to test. May revise rating up or down based on how this holds up. I plan to ultimately drive 140W of LEDs which is still well under the 80% rule but I'm already seeing this getting warm under 60W load. Not sure about longevity. Would benefit from a fan I'm sure but for my application I need a nearly silent power supply.

Used to power a string of LEDs around my projector screen. Amazing! Good valve for how strong this power supply is. Nice and quiet too!

I am working slowly on a project requiring, possibly, several LED strings at 5V. I didn't check this item immediately and when I did (on only a 3 Amp load), the P/S dropped over 10% on that load. Adjustment of the no-load voltage had no effect indicating that there were components not tested or evaluated properly at the factory. I will have to work with Amazon to return this product. If not, at the price, I will just have to eat this item. Fortunately, I have a 60A version to use which shows ZERO sag and holds perfect regulation at 3 Amps! Lesson: Always check products as soon as they are received. I have had a number of repacks lately that were suspect, by several vendors.
