The way I read the ANSI/IEC60601-1 standard this claims to conform to, these are standards which govern the /safety/ of electrical medical equipment that patients come in contact with. Low leakage, proper grounding, parameters like that. It doesn't necessarily guarantee or make any claims regarding the /performance/ of the device. That can be a different ballgame, especially if it's being used outside the environment it was perhaps designed or intended for (eg; outside in high humidity, sub-zero temps, hot temps, direct sunlight, etc and not in indoors at room temperature)

So I guess such certification is nice, but I don't think it makes something more (or less) appropriate for our kinds of use-cases, if that's what you're asking.

I don't think that, beyond a few basic stipulations, one needs to get fancy with their power supplies here. A quality regulated bench power supply that outputs 12-13.8VDC is what's needed. How much current it should be able to push is site-specific and up to your wallet. Bear in mind that you'll probably want an in-line buck-boost transformer to step the voltage up to 14-16VDC for your mount. Straight 12VDC in cold wether will make for some sluggish and hungry servo motors.
