Altec 9470A build
« on: December 05, 2019, 10:16:18 AM »
I have the set of 6 in trays with the power supply. Goal is to wire up 6 JLM Go Betweens, 150/600 switches on the inputs, and the Bourns 600 T pads on the outs. Question is, I want to take a tap off the +24VDC from the built in power supply, bring it up to 48 for the phantom on the Go Betweens...how would I do this? Manual says the supply can support 15 pres and puts out 2A, each module shouldn't exceed 130ma so I'm only at 780ma with the pres themselves.

Add one of the small Meanwell 48V enclosed switchers to the back of the rack.  I've written about them elsewhere here.

no, separate supply from the wall AC.
