Do enclosed switching power supplies follow any standard for their chassis size and mounting holes distances?
or each manufacturer has its own conventions?

  • \$\begingroup\$ There are a multitude of chassis shapes and sizes with a plethora of mounting options. That said, there are some standards out there which are followed - PC ATX power supplies have standard width/height and mounting holes, for instance. Some manufactures produce 1U-height 54mm and 86mm-wide power supplies with blind-mate connectors which allow for system integrators to use power supplies from different vendors as needed. \$\endgroup\$ – Adam Lawrence Jan 2 at 19:53

Not generally no, they don't have the same sizes or mounting patterns. On occasion some companies will match the mounting pattern and size to compete directly with a power supply. An exception to this is industry standard supplies like ATX or supplies that are built for 1U chassis ect.

It's a good idea to put a power supply on a bracket that attaches to a chassis in the event the power supply needs to be switched in a product. (I've had a few power supplies blow up and we had to find a replacement, and because we had a bracket we could make them field serviceable)
