I second Adams comments
I’ve used Powertech 7.5amp 12v power adapters for 5 years at two different locations on various mounts , EQ5 , HEQ5 and 2 off EQ6-R mounts and soon to be used on my new EQ8-R mount in June and with 230V extension leads up to 25m long with and without 4 and 5 way power boards and not one has failed yet , all mounts have operated perfectly
Can’t get any better reliable power source to your mount
I use them to power the mount , cameras , dew heated etc...
