My system will be using several blacet power supplies, and I was just wondering if, besidesthe functional/esthetical layout and total current draw, I had to consider possible issueswith powering some specific modules with others from the same psu (? my english isterrible, sorry)I think I've read somewhere that Blacet research's power supllies are very conservately run: is it allright using them at their maximum 500 mA ?thanks againstephane
Hi Stephane,
A while ago I was advised to try to put all digital modules (e.g. miniwave, metalbox digital noise, etc.) on one power supply. I did that for a while, but came to discover that I greatly preferred having modules where I wanted them rather than having to worry about which power supply they were using. I have noticed no ill effects since beginning to use both analog and digital modules on the same supply.
Yes, you can pretty much run the supplies up to their 500 mA limit, but when you get close to that limit, I've found that the Miniwave and Hylander ROM expander exhibit some weird behavior and stop working. A good rule of thumb is that one Blacet PS500 will power two frack racks of modules. Unless you have something insane like 5 time machines (Hi Rob), it's unlikely that you will come up with a combination that exceeds the 500 mA limit.
A technique that I came up with in my anal planning stages for my modular was to create a document which shows not only what modules I hope to add to the modular and where they'll go, but also how power distribution will be handled. I draw rectangles with the names of the modules, and note their power requirements on the respective rectangle. I add small rectangles to the side to represent the PS2CONNs, PS500s, and PS200s in my system. I shade them grey when I don't yet have the module, blue when they've been ordered, and white when the modules have been added to the modular. (Told you I'm anal.)
