48v DC Power Supply 400w 8.33A Waterproof AC110v/120v to 48vdc Converter Constant Voltage Outdoor Transformer for Pump Humidifier LED Lights

Happy with the product, hopefully these last some time.

I liked that this didn't have a noisy fan and yet still offered a robust output of 400 watts at 48v.

Using with Mikrotek RB500 routers. Great power source.

Wow almost burn my house I got lucky i didn’t no one was home.

Power supply puts out a solid 48 volts. I didn't have a load that would precisely pull 300 watts out of it but I did use it to power the bias circuit of a 50v device which draws approximately 2 amps and it worked fine. Not much noticeable increase in RFI but I didn't check the entire ham spectrum, and switchers like these tend to be noisy somewhere. Hopefully just not somewhere important!

This 48v power supply is built like a tank! It is surprisingly heavy. The input and output cords are thick. The case is aluminum. The build quality is excellent.The product photos are accurate.I have not pushed it to its rated wattage, but I have connected it to my dedicated tester. It did 150 watts continuous for an hour and got only barely perceptibly warm (+8 degrees F over ambient).If I were nit pick, I’d prefer the output cord be longer, but its length (9 inches) does match what’s listed in the product photos.

I was given this free to review. Take that into consideration.This is for someone seeking waterproof and durability. That super clean nice finish helps too.There are PLE NTY of supplies that are open cases, need a fan, are loud, and mot defenitely not water anythingTruly something you can use for Saltwater fish tanks or near a fountain or in myh case as a power supply feeding a buck bost converter36volts is kind of niche. For Leds it is not though. Regardless with the extra voltage you can do a lot.Even though it is 36v 8.33 amps I have it connected to two 10 amp bnalance chargers producing near 200 watts each. Without heat. NOW for only a sub 5 hour time.Anything without a fan is limitedRealistically if you only want power you wouldn't get this. There is something so nice though when your led saltwater project gets water on it and you do not have a panic attack.

This heavy duty supply is perfect for use with lighting. Using a balanced string of 10 seven watt lights wired in series so that three lines of 12 volts wiring up to 10 lights per line yields a draw of 36 volts. So far the power drawn is within the limits of the output. Recommended for ease of use and versatility.
