The only minus of the one I have is the 120 volt screws are out in the open and I had to make a cover for that. There is no off/on switch. Lambda "brick" supplies were like that. Still are, and they are 100% reliable. But as I've said before, "Pay ****, get ****." -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |

In article , says... I ordered one of these last week and it arrived today: shorturl.at/alQX6 I ordered the 24V 15A. Has anyone here used one? Pluses/minuses? I have not used one of those, but it seems that several companies make similar supplies. There are 2 companies ,one Maxwell and one Meanwell that make them. I don't recall which is the better, but the one that costs the most is better. I have one that I am using in a ham repeater and it has been in operation for about a year with no problems. I do not recall the price, but it was less than $ 100. The only minus of the one I have is the 120 volt screws are out in the open and I had to make a cover for that. There is no off/on switch. I decided to return it rather than take a chance on it. If it were going ot be outside or away from indoors, I might give it a try but the last thing I want is a toxic smoking end or worse. I must say I am a bit puzzled why these seem to have a bad rep. Aren't they switching supplies like used in desktop computers? Every desktop computer I ever had never had a power supply burn out. I've had about 7 over the last 3 decades and many have run 24 hours a day for nearly a year. If they can make them for PC's reliably, why not these devices? They are supposed to be designed for continuous duty too. |

Dell will come after you and see to it that you and your entire family disappear. On the other hand, if you sell direct to the consumer and someone dies.

Maybe, but in many cases, both units are being made by the Chinese. I have an old HP desktop power supply sitting here that I have used for several years outside of its original environment running 24/7 and it has done well. Made in China like the one I returned. I don't see a UL listing on it either. Ok, so maybe the cost is 2-3x more if I bought the PC power supply new. Well, I suppose that could be the answer. a 12V 24/7 PC supply at say $50 versus a 24V/15A supply for $17. |

BTW, the seller refunded me even before sending it back which tells me they probably have a lot of defective units. In good conscience, it is ready for pickup for the return, however, so even technically "free" now, I still won't take a chance. |
