Re: Mean Well power supply question

Dale Ghent

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.

Good point but that shouldn't be too hard to change - I'm more interested in what people think in terms of it being a medical rated supply and if this means anything in terms of it being higher quality than the run of the mill supply.

Hi Mike,

This power adapter has strange DC connector. It shows 4-Pin DIN Male connector which is unusual for this hobby.

What about this style DC switching medical supply from Meanwell?

Thank You,
