Pedalboard Power Conversion

[Dylfish]

Hey Guys,

While not exactly a pedal question I wonder if anyone could give their expertise on this.

I am building a pedalboard from scratch with all inbuilt input, output and power outlets to keep it all compact. I used a JP-02 power supply, which uses a 18v 1A wall wart to power it along. I am looking at having a IEC connector in the pedalbaord to connect the AC to a embedded SMPS powersupply which outputs 18v @ 1.1A. and then then DC output connected to the power supply via a 2.1mm center negative plug.

Apart from the AC danger issues (my qualified electrician mate will help with this.) are there any other issues you guys can see with this? Noise? Interference? Heat maybe?

This is the power supply im thinking of using.

and this is how I'm imagining it in my head.


Thanks!

It is an obvious shock hazard.

I would expect an open-frame switcher supply to throw supersonic hash for several feet around. Supersonics have a way of aliasing into the audio band and messing your audio.

Perhaps your sparky has a metal box and some secure way of mounting the PCB.

ahh ok

would using something like this be more appropriate (an 18v model) or could you suggest a better method?

Better:
use two sealed lead acid batteries under your board and one sealed lead acid battery charger to charge them
