No. You wanna stick more volts into all your devices to see which ones fail and which ones don't ? Or are you just happy to advise other people to ? Stick to selling music-centres. geoff |

You can all rest with a less burdened mind in
that I did find a suitable supply at Fry's near my home. I didn't just go there first, because I normally don't see universal adapters with such high wattage. I found just one that had the desired amps, at 2.5 with a stop at 5V, and one of the plugs fit snugly. $19. Tobiah On 07/01/2014 09:21 AM, Tobiah wrote: I got an audio interface off of ebay that didn't come with a power supply. The manual says it's a 5V 2A DC output. I started looking for a replacement and didn't find much out there. I see hundreds on ebay, but my experience is that ebay is a very poor source for memory, batteries and power supplies. I recently got 3 usb chargers off ebay from two different vendors that were rated at 2.1 amps, but would only deliver 300-500ma. I know that there are many name brand counterfeits on ebay for batteries and power supplies. There were many auctions that called out my exact interface: "Power supply for M-Audio Fast Track Ultra". Then I'd zoom into the photo and see that the supply was rated at 500ma, or 4 volts, etc. So the question is, aside from finding an OEM, which would be cool, where can I go to get such a power supply where I can trust that the device ratings will be accurate. Thanks, Toby |

Then I tried to find a linear power adapter at Mouser, and found this: http://www.mouser.com/ds/2/410/WDU9-300-224465.pdf The datasheet contains this: "U.S. DOE Compliance per Sec. 301 of EISA 2007: As of July 1, 2008, this product is intended for use as follows: 1. Requires Federal Food and Drug Administration listing and approval as a medical device in accordance with section 513 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360c) 2. Powers the charger of a detachable battery pack or charges the battery of a product that is fully or primarily motor operated. 3. As a service part or a spare part for an end-use product manufactured before July 1, 2008, that constitutes the primary load of this power supply." The model is listed at Mouser as "NRND" = Not Recommended for New Designs. |

But when someone derives a connotation from your writing, you throw a hissy little tantrum and tell them to read what you wrote. You don't seem to understand that what you infer is very frequently not actually implied by the writer. What /you/ don't understand is that what the writer /meant/ to say doesn't matter. It's what's actually on the page. And that's what we have here -- a blanket statement about the universal unsuitability of 6V power supplies for all 5V devices, which anyone who's had a reasonable amount of electronics experience knows isn't true. I am (horrors!) sometimes guilty of sloppy writing. But when I say "read what I wrote", it's because people are carelessly or deliberately misreading it -- not because I didn't consciously say what I meant. Your hallucination that you're always right overwhelms your ability to reason, so you start blubbering and pontificating. As entertainment, it's on a par with a bad sitcom. Get a laugh track, li'l buddy. We keep coming back to this, your claim that I said I was always right. I never said any such thing, and (amazingly) you've correctly quoted me: "I'm (almost) always right." averring that the "almost" doesn't count. Here's a scene with your fourth-grade English teacher: "Captain Corcoran sings that he's "hardly ever sick at sea". What does he mean, class? That... He's never sick. He's on occasion sick. He's always sick. ?" None's hand goes up, flapping as his body shakes. The teacher sighs. "Yes, St Vitus?" "He means he's always sick." "How do you figure that?" "Well, he says he's sick at sea." "What about the 'hardly ever'?" "Doesn't matter. He said 'sick at sea'." "So you can just ignore the 'hardly ever'?" "Of course." Fifty years ago, I got 800+ on my math SAT, and 765 (I think) on English. * Throughout college I got As in my English courses. (And I'm an EE.) Don't tell me I don't understand words, or their meanings, or how those meanings interact to convey ideas (intentionally or unintentionally, literal or implied). And as for fantasies... Yours about my not having a job because I'm a poor writer, and not having any friends (for unstated reasons) -- from what Wonderland do they descend from? Everyone has problems. One of mine is the urge to respond to idiots. I shouldn't, but I figure if I don't, I've implicitly given in to their attacks. Perhaps some day one of my remarks will hit home, and None will seek out the professional treatment he needs -- to find out why he has nothing better to do than to pointlessly spew ad hominem attacks on people he doesn't know. * The reason for such a "low" English score appears to have been those "analogy" questions. They're the only questions, on any type of test I've ever taken, that gave me trouble. I often found myself trying to distinguish between two answers that seemed only subtly different from each other. As far as I know, the analogy questions were dropped from the SAT several years ago. But I had no trouble finding this page: http://www.onlinetestprep.com/engine/analogy.asp |

... What /you/ don't understand is that what the writer /meant/ to say doesn't matter. It's what's actually on the page. Your inferences and your own opinions about connotations are not on the page. And that's what we have here -- a blanket statement about the universal unsuitability of 6V power supplies for all 5V devices, which anyone who's had a reasonable amount of electronics experience knows isn't true. Your inference about universality is your own problem I am (horrors!) sometimes guilty of sloppy writing. But when I say "read what I wrote", it's because people are carelessly or deliberately misreading it -- not because I didn't consciously say what I meant. Yeah, your sloppy writing is everyone else's fault, despite what you actually put on the page. Did you even read what you wrote? "It's what's actually on the page." Read what you wrote. Of course, what you wrote may be very wrong, but you aren't honest enough to deal with that obvious fact. Your hallucination that you're always right overwhelms your ability to reason, so you start blubbering and pontificating. As entertainment, it's on a par with a bad sitcom. Get a laugh track, li'l buddy. We keep coming back to this, your claim that I said I was always right. I never said any such thing, and (amazingly) you've correctly quoted me: "I'm (almost) always right." averring that the "almost" doesn't count. Read what you wrote: "Sorry, but I am always always right." Are you in denial? And are you denying that you set off the "almost" in parentheses, or slashes (poor writing, that), to distance it from yourself and your bloated claim as if the "almost" is of less important than the rest of the claim? Read what you wrote: "Sorry, but I am always always right." Here's a scene with your fourth-grade English teacher: No, it's scene from some fantasy world in which you're hiding. "Captain Corcoran sings that he's "hardly ever sick at sea". ... flush li'l Willie's fantasy from his school days "Of course." What that elaborate fantasy has to do with reality is anybody's guess, but it's based more on your own fertile imagination than any reality. It's pretty easy to tell what fertilizes your imagination, including big piles of bovine manure. Fifty years ago, I got 800+ on my math SAT, and 765 (I think) on English. * Well, aren't you impressed with yourself! Throughout college I got As in my English courses. (And I'm an EE.) Don't tell me I don't understand words, or their meanings, or how those meanings interact to convey ideas (intentionally or unintentionally, literal or implied). I'll tell you whatever I like, Willie. You have no authority here. Bragging about how smart you used to be doesn't give you any power over me, and it doesn't make you always right. |

I've got an awful lot of them here, without problems. Although I do have RCBOs. Which would tend to minimise the problem over a whole house RCD. The only real answer is to either develop smart RCDs that only respond to in-phase currents or increase the trip threshold. These things have to be cheap, so it will be the latter. If you increase the trip threshold it defeats the object? -- *Dancing is a perpendicular expression of a horizontal desire * Dave Plowman London SW To e-mail, change noise into sound. |
