Hey Guys.
just got a question i wanted to ask, couldn't find the answer in any of the other topics, sorry.
im running a group of 8 pedals and using the PSA series adapter along with a PCS-20A daisy chain, but as the PSA adapter only supplies upto 200ma, occassionally the pedals current draw will exceed 200ma and the pedals wont get full power, some wont even switch on. I'm thinking, i have a TU-2 and an NS-2 both connected to the chain, the PSA adapter is currently plugged in through the TU-2. if i added another PSA adapter to the NS-2 and connected the PCS-20A to the outputs of both the NS-2 and the TU-2 is this going to cause any electricial issues at all and cause any damage?
i'm trying to avoid having to use generic power adapters/daisy chains to solve my issue.
any advice would be great, thanks!
Scott. |

| I know you said you were wanting to stick with Boss adaptors, but you should really look into Visual Sounds 1-Spot as it can supposedly power up to 20 pedals from just one AC adaptor, as long as you get enough daisy-chain cables...And it is also compatible with both different types of Boss power supplies. |

Yes.. you can use two adaptors.
One on the TU-2 and the other on the NS-2
One for each group of 4 pedals, but using also two daisy chains separated.
I'm using also 8 pedals and one psa adaptor and it takes care of the load very well. |

hi stomp. all i recommend is dont go over 200mA . like jack said there are other adaptors out there. for one of my chains im running 250mA so im using a 300mA adaptor on that one.
i dont know if adding another Adaptor to your NS-2 will help. thats a good question. i dont think it would damage any pedals but could that possibly wear out your daisy chain?
how much mA exactly does your chain require? if you have a real sucker in there (PS-5, RV-2) try running your second AC to that one since it will take a load off the rest of your chain. i used to do this with my RV-2 and it brought the rest of the chain below 200mA.
but i think the ideal way would be to buy another daisy chain. |

Is there any diffrence between Daisy Chain for PSA and ACA? Do they both work the same?

| yeah i've got some power suckers in there like the TU-2 PS-5 and the DD-6 which hog most of the supply. i'll keep looking around, though running 2x PSA power adapters and 2x PCS-20A might be the best way to go. Thanks Guys! |

Danelectro makes a daisychain for five pedals also. One end goes in the 9v adapter and the five ends are ready to go.
In case you don't want to use a NS-2/TU-2/PSM-5/batteries/hamsters for your setup. I like it as a backup when Im just going with just a few pedals, or when I got my 8 Boss and a Wah to spread the draw.
Also heard the DD-3 power draw varies from 45-65 depending on use.
Don't know about the other DDs tho
Pretty safe to use multiple adapters, just make sure they're plugged into the same powerbar- a one-hit-kill-switch |

If you are keen on sticking with Boss products then you should look at the BCB-60 as the AC adaptor that comes with it is a 1000mA one! 
Should be enough power for what you are looking at.  |

Wow even with 1000Ma you could power about 24 pedals of various draw
but you would still need to daisychain them together
'course the Danelectro d-chain (its just a chain, no p/s attached)can also be hooked up to the 1KMa adapter, but only does five pedals, where as the Boss one can do seven additional, but you need a a PSM-NS-TU pedal as well

1KmA or just 1 amp? i'll let you think about that one!
the thing is, you couldn't even use the PSM/NS-2/TU-2/LS-2 cos all of those pedals have a warning on them not to put more than 200mA through the pedal as this can overload it i was thinking of getting a BCB-60 but have now decided im customer making my own pedal board with patch cables and powered daisy chain etc. |

Hi Stomp98
Please don't think that I am insulting your intelligence, but what they mean, is that you shouldn't draw more that 200mA of current from-through the PSM-5 pedal.
Not PUT more that 200mA into it, electronic circuits only draw the current that they need.
As an example, on my test bench, I have a 5 Amp power supply, that I use when I am testing-repairing pedals & other stuff, I leave the current limit at about 2 amps unless I think the pedal-whatever, has a problem that will make it draw excessive current.
The circuit under test, only draws what it needs.
As for the Voltage setting, I limit this to what is required by the various circuits that I test.
While I don't have a PSM-5, I think the current limit that you we are talking about,,
Is more a function & limitation of the PSA adapter, which has a current limit of about 300mA.
I think that the power send (9V In-Out) on the PSM-5 is just a pass through connector --- but I may be wrong, I don't have a schematic, to verify this.
Does anyone have a schematic for the PSM-5?
Hope this helps...
And I hope I wrote what I think I was trying to say & explain. 
Regards Dr, Bob |

hey Dr. Bob. yeah i can understand what your saying. im no electrician so im not really sure of the technicalities but the way i saw it was like this:
1. you plug a 5 Amp power supply into the power input of your TU-2, it only draws the 50mA or so that it needs to run, you got no problems.
2. you plug a 5 Amp power supply into the power input of your TU-2, and then you plug a daisy chain into the power output of the TU-2 and try and run more than 200mA through it you run into problems. i guess from how i was seeing it, from an electrical current point of view i sort of saw the TU-2 as more so a tunnel the power goes through to get into the daisy chain (whilst powering the TU-2) and power your other pedals. the way it was described to me was that the TU-2 "tunnel" (or circutry or whatever you call it) could only take the 200mA, and if you tried to take more than the 200mA through it thats when you caused the issues.
if i've got it wrong let me know at least i've learned something! but that was what i was trying to say in my prev post. |
