I read on here some discussion about the strict voltage requirements for the WD-20. It was said (I think) by WarpAstron’s support that the mount could be damaged if it is powered by more than 12Vdc. In my case I wanted to use a regulated 10 amp power supply but it delivers 13.8 Vdc. So I will have to get into my power supplies guts in hope there is a voltage trim pot that I can adjust to drop its voltage down to the required 12 Vdc. If not I will have to go on the hunt to find one that fits the requirements.
It seems odd to me however that this mount has such a stringent voltage requirement, and that spec is not directly stated in the literature that comes with the mount. Also that spec should be very evident on their website to give prospective customers time to source such a power supply.
I suspect WarpAstron may be overly cautious with such a strict spec but better to be safe than sorry.
It should be noted by this mounts owners that when sourcing a power supply look for one that stipulates a full load output of 12Vdc, many PS’s have a different no load vs full load voltage spec.
I am glad that I ran across that discussion on Discord. That is what WarpAstron support says. I was going to use a Pyramid power supply (13.8v) to run my WD-20. I can still do that but I will run the power from the Pyramid to a Pegasus Astro Pocket Powerbox Advance. It has a regulated variable voltage output port that can do 3, 5, 8, 9, or 12v…

I have not sorted my power supply issue yet, I also plan to use a Pyramid 12 Amp dc PS but it’s output is also 13.8 Vdc, so I plan to get me one of these from Amazon and wire it into the PS case to give me stable 12 Vdc.
In my case being in Canada you may have to fudge this link:
Note you might see an equivalent buck converter that’s even cheaper if you look around, just be sure it can handle the current, in my case 12 amps. I plan to use this one PS to power everything from the mount up, dew heaters etc take a lot of power.
