Re: [Doepfer_a100] buss board +/-15V

2009-01-12 by Laurie Biddulph

I would check with Dopefer to see if they can advise you of the current 
capacity of their bussboard but I would expect it to be in excess of 1A so 
your requirements shouldn't be a problem.

If the clock module has decent isolation on it's power rail then there 
should be little or no `leakage' back up the bussboard so in theory you 
shouldn't have a problem. Being on a separate rail is a good idea and would 
further reduce and potential problems.

If there is only the one device being connected to the dirty 15V then you 
might, in the long run, be better off connecting it directly at the power 
supply end of the bussboard or to the power supply itself. This gives a star 
connection which is far superior at minimising noise problems.
