Only the "H" series have this option. the common AM882 is only DC.

The cheap ones with AC/DC options don't handle it very well at all in my experience but better ones which often only have AC option I've never had a problem with. Much prefer to use DC supply with Caps on a fast router with decent weight gantry.

Jazz, could you help me with my powerbox project, I got the same Lichuan Drivers and Motors as you did, but I am having some trouble finding some help on the installation. Could you share some of you project? You would help me a lot. Have you ever shared your project with anyone? I could not find anything here. my e-mail is [email protected] I really hope that you could help me with this! Thank you so much! And I will be looking forward to your reply!
