其實市售電源供應器都有INPUT OUTPUT的功能,所以如果沒有要用電源供應器做IN OUT或其他的一些功能 的或,只要把9V變壓器(電流約300mA到600mA)和一對多的電源線接在一起就可以做電源供應了,電源供應原理就是這樣子 小弟淺見.......
例如現在只用一顆boss效果器就用一顆9.6v的boss變壓器 ,但是如果現在用兩顆的話,就要兩個boss 9.6v變壓器.. 但是如果把一顆boss 9.6v變壓器的output接成兩個並聯輸出那就可以供應兩顆boss的效果器, 換句話說,如果把整排電源線都跟boss 9.6v變壓器output作並聯輸出,加上原來變壓器上的輸出,全部加起來就可以供應9顆boss效果器!!........不知道降講會不會很模糊! 小弟淺見.....
請確認你所謂9V變壓器有穩壓功能，否則換來的是雜訊而已。所以我網站上的電源穩壓模組就適合搭配市面上沒有穩壓作用的變壓器。 不過說真的，個人認為要用電源供應器的話，要選有多種電壓輸出以及獨立供電的機種。所以有一些沒有獨立供電的電源供應器就不用考慮了。還不如用分接的方式就好了，簡單又便宜。不需要花三千元去 買分接式的電源產品。 我網站上的設計只是陽春型的。網友可以參考該設計自行變更成獨立的供電系統。
jealousydod and all, 以下你可能已經想到了，但討論區有些網友並不一定清楚，所以補充一下。並不是要餵幾個效果器，便無限制地拉幾條排線；AC/DC adaptor不是完美電源，接越多負載，壓降就會更嚴重，結果跟電池快沒電(內阻上升)是一樣的(雖說有人喜歡這樣，例如Eric Johnson......)。此外，所有與110V電源直接相關的電路皆有一定具體危險，光一顆1000uF的濾波電容器就足以電昏一個大人，無誠誤試。 p.s. ─以上精華區可能通通有，再不用搜尋功能找找...... ─我可能有點偏執，但再次強調：雖然通俗用法的"變壓器"一詞，含一切將110Vac轉為小電壓(不論是ac or dc)的器材。但精確而言變壓器(transformer)與AC/DC adaptor是不同的。一顆adaptor內可能會有變壓器這個基本電子零件，但光一顆變壓器絕不可能提供直流電的。
that sort of ad/dc station. only convert 9V ac to 9V dc for pedals. padel power 2 seems a bit too pricy. coz i plan to use it with a rocktron power station.
To mbv My "Pedal Power" voltage regulator may suit all that you need. You can have as many output jacks as you like. Just connect all DC jacks in parallel. But my design is not the CAJ design so I can't guarantee that they will have the same performance.
if the DC power supply output 9V-200mA, and then you connect 6 effect pedel use a parellel circult; each current consumption is 20mA, so is it will also decrease voltage or like a 9V battery coming "dead"? but the total output of the DC power supply is 200mA!
To zak There is an important factor called "Load Regulation". It means that more current draw will result in more voltage drop. Because there is always some internal resistance in the power supply circuit and the regulator IC. 200mA only means that it will operate in full load condition(200mA) for a long time without any damage. Load regulation can be culculated. The datasheet of any regulator IC will also give you the full spec. including "Load Regulation". If you do care about the voltage drop when using parallel connection, just try the voodoo lab "Pedal Power II" DC power supply for effect pedals.Each output is isolated from each other.So the load regulation will be small. Also, "dead battery" can be emulated by simply turning a pot.
