Isolated power question

[pine]

Hi,
I searched on this but didn't find the answer I was looking for:
If I use a regular Belkin power strip, surge protected (model BP108200-06 if that matters), and individually plug in the DC adapters for each different pedal, are those then considered to be isolated power supplies or in a daisy chain? I know the strip has a common ground for each outlet, but none of the adapters are 3-prong.

Thanks in advance for the help

You'd be better off getting something like this:

As per your question, while you are technically plugging in each effect separately by using its own wall wart, you're still using a daisy chain method, since the power strip doesn't have isolated inputs. Even the Tripp-lite doesn't offer this but, it has a higher level of surge protection.

Personally, you would be better off getting a dedicated PSU for all your pedals and powering them by connecting the PSU to the Belkin instead of using the wall warts.

What kind of pedals are you powering with wall warts?

I've got a Strymon El Capistan, and a Boss FRV reverb pedal, occasionally a Keely Compressor and a Wampler Tweed . I'm not working with an unlimited budget so I'm trying to do the power supply thing on the cheap.

This isn't correct, it is not the same thing as daisy chaining 9vdc pedals. The AC input side of transformers aren't isolated on any of the commercial power supplies. You'd need a **** load of stuff to have individual "isolated" AC input supply - something like a UPS power conditioner for each pedal.

To the OP, you should be fine with this method. You may need to experiment with placement, if you notice any hum. The wall warts aren't shielded, I'd suggest testing by spreading them out among several outlets/strips/extension cords, check that no noise is induced. Then put them all in one strip, check that there is no noise increase. If you do notice any added noise, try moving them one at time, re-orienting 90º relative to each other can help. You can get the little short extension cords sometimes called "wall wart eliminators" that would let you place them wherever needed.

Thanks, that was what I was hoping was the case. The Belkin power strip has outlets on it that move around so the wall warts can all fit alongside one another, hopefully that will allow me some flexibility with orientation. Then I'll put the whole thing in a box and label the DC lines and have a ghetto iso power supply for under $30
