diy led power supply

[coralbeauties]

I need some advise or recommendation on a power supply for my led lighting. I have 204 3watt leds and am currently using a meanwell 1000-48 power supply. I ran this one for over a year and it failed. I replaced it with the same model (new one off ebay) It has only lasted a month. I would like to know which supply you would recommend or stay with what I have and have it repaired or replaced.
thanks
Jeff

What's the exact model number of Meanwell power supply you're using? How do you have the LEDs wired? Are you using a driver like the Meanwell LDD?

running a rsp 1000-48. I have all my leds on not more then 12 led strings and am using ldd drivers with a jardurino controller. I am guessing maybe I got a bad power supply. I tried to call meanwell today about getting it fixed but got voicemail will no call back. Can anyone tell me the difference between the rsp 1000-48 model and the se 1000-48 model would be? Looks as if I will need to buy another unit till I can get things sorted out with the one that went bad.
thanks

Main difference offhand is the rsp is designed to do current sharing so you can parallel a bunch (4).
Also has a 5V out channel..remote sense..auto sense on AC side.

nothing in part. you really need.. maybe the 5v rail..

So you have 17 strings of LEDs, with each string containing 12 LEDs? There shouldn't be a capacity issue. 17 strings of LEDs at 1A each = 17A total. The voltage shouldn't be a problem either. At 12 diodes per string, that's 36V per string, which leaves plenty of voltage to power the drivers.

Not sure why your power supplies are dying so early. You're running probably 600W of LEDs on a 1000W supply, so you're not running it too hard. Maybe the supply is getting hot? Does the supply have a fan in it? Not sure what else the problem could be.

so given my set up will the es 1000-48 work just as well? Sells for a good $50 less.

The more advise I am getting sounds like I just got a bad power supply. The original supply I had was used when I got it and is hard telling how old it was when I bought it.
