Talk:Dummy load

This article had templates indicating it should cite its sources and that it needed technical cleanup. I have rewritten it to provide citations for most of the information, a and I think the remaining information is obvious to anyone who is familiar with radio transmitters. If someone can find supporting citations, that would be great, but the sources I have take quite a bit for granted. I also think the first paragraph now makes it clear that this topic is for people interested in technical information related to radio transmitters. Gerry Ashton 20:06, 25 July 2006 (UTC)

There are other uses for dummy loads. loudspeaker models, for instance, or Wind_turbine#Electrical_braking — Omegatron 21:06, 9 November 2006 (UTC)

Function Principle

If there are any questions or remarks regarding the new subsection Dummy_load#Function_Principle don't hesitate talking to me. If you're interested in the circuit drawing, I can also send the dia file. --Robb The Physicist (talk) 09:32, 9 September 2008 (UTC)

I removed the section that was added because it does not adequately explain how the circuit would be used as a dummy load. Understand that the term "dummy load" refers to something that would be temporarily connected to a complete working device (an amplifier, for example) to simulate the load that would be attached when the device is in normal use, but has some advantage over the normal working load. Those advantages might include

• • Not radiating radio energy
  • Not driving the laboratory workers nuts with intense sound from a loudspeaker
  • Better instrumentation

After testing is complete, the dummy load would be disconnected, a useful load would be connected in its place, and the device would be placed in service.

The circuit that was described in the "Function Principle" section seemed like it would be a permanant part of a larger circuit, and thus would not qualify as a dummy load. --Gerry Ashton (talk) 16:59, 9 September 2008 (UTC)

OK, to make things clear: The function principle refers more to an electronic load, but this article refers here. I understood an electronic load as a dummy load for simulating a real load, e.g. for testing power supplies. The very schematic circuit drawing I presented should show the very simple idea how to understand and realize such a load. But since I'm no expert in this field, what did I misunderstand? I'm currently learning a lot about electronics and there is much more to discover, I know. --Robb The Physicist (talk) 17:26, 10 September 2008 (UTC)

The dummy loads described in the article can simulate many different actual loads. This article generally describes what kind of loads are available and what they are used for. What is the load you described supposed to accomplish? Does anyone sell them? If no manufacturer considers them important enough to sell, maybe it isn't worth covering in the article either. --Gerry Ashton (talk) 17:33, 10 September 2008 (UTC)

Well, I don't know if anybody sells such kind of electronic loads, but there are several pages around in the web with circuit diagrams based on this function principle, e.g. [1], [2] (both in German). The first one describes real world products, the second one describes a self-made load. Maybe we talk about different things? When I read an article about dummy loads, I'd also want to know something about the way they work. --Robb The Physicist (talk) 09:34, 11 September 2008 (UTC)

For some of the loads described in the article, there isn't much to say about how they work, they are just resistors. If you want to describe how the load in your diagram works, you would have to first explain what its application is, and then describe how it works. What would be the purpose of the load you showed. Is it a constant current, a constant voltage, or what. Can it sink current, source current, or both? --Gerry Ashton (talk) 14:47, 11 September 2008 (UTC)

I see. OK, this requires some research for me to explain it, but I'll do the job. AFAIK it provides a constant current load e.g. for load tests of power supplies. Thanks a lot so far. --Robb The Physicist (talk) 11:06, 12 September 2008 (UTC)

Image of Programmable Dummy Load

With all due respect, I posted an image next to the Audio section displaying a product that is relevant to the subject. The image was twice removed by Binksternet. After I reverted it back, I stated: (Please state reason for a revert so changes can be made appropriately.) my reply was: (Image is promotional). Please could Binksternet answer my initial question by giving me a bit more info as to why the image is promotional? What elements of the image are promotional so that the image can be changed? Why have the other images on the page (which are also certainly in the "promotional" catagory from Binksternet's point of view) not been reverted!? The image and post are purely informative. Please explain your reasons in more detail. Best Regards. —Preceding unsigned comment added by Ali66b (talk • contribs) 15:20, 29 June 2010 (UTC)

One sometimes sees an account created and sees that all the edits by the new editor promote a particular company or product. One naturally suspects there may be a conflict of interest. The edits by Ali66b fit the pattern in the sense that all the edits promote the HotBox, but on the other hand, the conflict-of-interest editors usually plaster their hype on every article that is even remotely related. Ali66b's edits do not fit the pattern in that sense, because his/her edits have been limited to this article. Jc3s5h (talk) 15:31, 29 June 2010 (UTC)

Hi Jc3s5h, I see both your point's of view. The content I have posted is no better/worse than the other posts on the page so I personally think that the picture should be allowed. I am an audio engineer truly interested in new audio technologies and thought that this might be a good starting point for a wiki, I know my "credentials" as a wiki writer is non-existant, but an editor has to start somewhere! I do plan to write more in the area of audio and DSP technologies in the near future. —Preceding unsigned comment added by Ali66b (talk • contribs) 16:05, 29 June 2010 (UTC)
