  • Commercial power supply switchover circuits can be added to set up a redundant motor drive configuration with commercially supplied power.
    (Requires the addition of at least one commercial power supply switching circuit board to the main circuit.)

  • During operation, the switchover between commercial power supply and inverter operation is performed shock-free, and synchronized or split operation is possible. (Optional functions: An ACL is required on the output side.)
