5V70A 350W DC Converter

Bought for LED sign worked well to replace original installed power supplies

Has worked flawlessly, but I need to find a nice project box for it and the related hardware.

This pwr supply has 3 different channels, so you can run 3 different strings of the same voltage rating. If your cooling fan is running constantly, check the output voltage (mine was at 30v out of box). Adjust the potentiometer where it says adj -> +V. If the fan is loud check the case (might’ve been pushed in during milling), or add washers between the case and fan. Hope this helps some of you, and I’ll probably review again after a few months of use.

So far both power supplies I purchased are good. One of them came with the side of bent as pictured in other reviews but so far it works fine and no need for replacement.

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.

My power supply died in my 3D printer a few months after using it. I pulled the specs and this was the exact same supply. It was a little more expensive than a few others but the ratings were considerably better. I had no issues swapping out the two. The screw holes almost lined up perfectly. It is on the 2nd print and doing great. Soon, I will do the real test that the other supply failed and run it for a few days 🤞

Very good quality. Clean 12v power. I have only run it at 15 Amp output to date. Output can be adjusted slightly with a trim pot on the unit. No power switch

The input voltage switch is inside the cover, and there is a sticker saying "Don't open the cover". Fortunately I could see the switch through the cover holes and it was set to the correct input voltage.There is a POT to adjust the output voltage. I set to 5V and then started adding load. My PLC ran OK until I connected an LED strip, then my PLC smoked. I think the voltage jumped. I would not recommend connecting directly to digital circuits. It needs a voltage regulator.The power supply is lightweight and easy to connect AC cord and DC wires. 20A can drive a lot of LEDs.

Love it and can adjust voltage

Easy to set up, good buy

After a poor experience with a laptop charger type of PSU from this brand I was pleasantly surprised to find this to be significantly better. I don't have a load to be able to test it up to the full 20A at the moment but a brief test at 10A and longer tests at 2-5A showed less than 10mV drop on load vs. off load. The output is also adjustable over a reasonable range, so if you want to push it a little over 5V to compensate for some wiring loss in getting to your device then you can. Just make sure your device is happy with that little extra voltage for the case when it's not pulling current (e.g. at start up).I'm using it continuously powered but not using it at anything like 20A (<9A) so it's warm but quite comfortable. You would probably need to be careful about cooling if you were going to run it flat out for an extended period.NB. There appear to be several sellers offering what looks to be the identical PSU under a variety of different brands (spec. and pictures look identical). I just went for the cheapest.
