AinsleyWalker Posted November 26, 2015 Share Posted November 26, 2015 I have a Nordell Audio Power Core, great little power supply. It has seven 100mA outputs and one 500mA output, along with 3 higher voltage outputs which I don't use/won't use any time soon. My issue is I have/will have 9 pedals on my board. One can be powered off of my TU3, which leaves 8 pedals to be powered from the power supply(including the tuner) I'm wondering if it'll be safe to use the 500mA output for one of the pedals on my board, perhaps the TU3? The instruction booklet states that this output produces a MAX current of 500mA and is 'suitable for digital effects'. I know nothing about anything circuit/electrical related so I was hoping someone could give me their opinion as to whether this output is safe to use on a standard Boss pedal(that will be powering another pedal too) or another pedal on its own?

ahpook Posted November 26, 2015 Share Posted November 26, 2015 (edited) It'll be fine...the pedal will take what it needs from the supply. The figure of 500mA is an idea of the maximum current it can deliver if needs be. Edited November 26, 2015 by ahpook Quote Link to comment Share on other sites More sharing options...

The plug socket is working fine and so are all the pedals, it's isolated to the power supply. I've contacted the seller. This wouldn't be because I was running the tuner (and another boss pedal off the tuner) from the 500mA output would it.... Quote Link to comment Share on other sites More sharing options...

fleabag Posted January 3, 2016 Share Posted January 3, 2016 For a pedal to only take what millamps it needs, doesnt the PS need to be the regulated kind ? Quote Link to comment Share on other sites More sharing options...
AinsleyWalker Posted January 5, 2016 Author Share Posted January 5, 2016 It's cool I'm just not going to use that output this time, and use separate power supplies for any other pedals needed. Quote Link to comment Share on other sites More sharing options...

[/quote] Nope. The current drawn is dictated by the item thats drawing the current. Think of your household ring main. It'll probably be on a 16A breaker but a 60w table lamp plugged into it will only draw about 4A, not the 16A available to it. A regulated power supply just keeps the output voltage constant as the load on it increases (up to its rated maximum load). Quote Link to comment Share on other sites More sharing options...
fleabag Posted January 5, 2016 Share Posted January 5, 2016 Ah, thanks. Good to know, because whenever i've bought them in the past, i've always gone for the regulated kind Is there any advantage at all in regulated supplies for pedals ?

Example is wrong. Ring Main uses 30A breaker. 60-watt light bulb draws 0.25-Amp. Quote Link to comment Share on other sites More sharing options...
