I have a Powerwerx 12V, 30A power supply.  The actual output voltage is 14.1V. Is this okay to use to power my 12V equipment such as cameras, focuser, etc?

I've been using 13.8 volt pyramid power supplies for about 6 years now and never had a problem with any component. A regular lead/acid battery will put out 13.3 volts and many people power their systems with these.

Yes, that shouldn't be a problem at all. Most "12 volt" power supplies are close to 13.8v, so that's a smidgen high, but not a problem.

I thought it would be ok but I wanted to make sure. Thanks so much for your replies. I appreciate it.

I also have a 30 amp Powerwerx power supply.  My voltage was a bit low.  I think it was KathyAstro, in one of her videos, who talked about being able to change the output voltage (within a small range) on these units.  I was able to increase mine a bit to get it closer to 13.8.

I have been using that exact power supply for several years with no ill effects.  "12v" is a nominal standard only.  Most 12v power supplies deliver well over 12v so that they can charge a nominally-12v battery.

That wasn't me, but I remember that thread.  There is apparently an adjustment inside the device.
