    • Why 25V? The control box of 10 Micron mounts can work with 24V up to a maximum of 27V. Since 24V power supplies can occasionally drop below 24V at high loads and low temperatures - which can lead to the failure of the control computer - the power supplies for GM 2000 HPS, GM 3000 HPS and GM 4000 HPS are therefore preset to 25V. This value has proven itself over the years.
    • Output via 4mm banana sockets, fitting for the 10 Micron power cables that come with the mount
