500 Series in a cabinet

The key word(s) here is "large cabinet". The power supplies I use have been around since 1972. They are an "industry standard" size with common terminals and mounting holes. There are 2 large companies that make these: Power-One and Condor. I use the Power-One because it has a higher "build quality". These supplies are available all over the world. They are big and heavy. So, if you are building a "large cabinet", and you want to power many modules of all types, then buy the HCAA-60W-A model (about $85 if you shop around). I will make a MOTM-980 Power Distribution board that has all the needed connectors. There are several reasons why I don't provide a "front panel remote" power switch: a) volume/cost. The demand is probably less than 20/yr. b) tooling/cost. I'd have to make up another set of AC wiring sets, and I have to order a min. of 50 sets. c) it's not *that* big of a deal. Really! I rear-mount my supply, and use a power strip to turn it off and on. d) safety issues due to the fact I sell kits. Having all the wiring "self-contained" on a MOTM-900 module means that I can control exactly how it's done. Every cabinet will have different depths/different power supplies. Then there is the 120/240V issues, etc. I have to assume that *no one* can wire up AC, even though there are many folks that can. But I am in the *liable* position, not you :) There are 100's of UL issues on AC wiring that I have covered in the MOTM-900 kit, even though it *appears* like hardly anything is there at all. I like nice big cabinets, too. But they are just not practical from a shipping/stocking standpoint (for me). Paul S.
