230 VAC Power Source Requirements<\/h2>\n\n\n\n
    \n
  1. 230 VAC (nominal), 1 Phase, 50\/60 Hz, 30 A<\/li>\n\n\n\n
  2. For installations of more than one Seakeeper<\/span><\/span>, a separate circuit breaker should be used for each Seakeeper<\/span><\/span> Motor Drive Box.<\/li>\n<\/ol>\n\n\n\n

    Spool-Up Power Modes<\/h2>\n\n\n\n

    The Seakeeper<\/span> 10.5 is factory-configured for Default Spool mode, which accelerates the flywheel to operating speed (8700 RPM) in 40 minutes. This mode requires a higher AC power draw during startup (4000 W) but reduces the overall startup duration. For vessels with limited generator capacity or where minimizing peak electrical load is preferred, an optional Low-Power Spool mode can be selected on the display’s Settings page. This mode reduces the startup power demand to only 3500 W, which increases the time required for the flywheel to reach operating speed. Select the spool mode appropriate for the vessel’s electrical system to ensure reliable operation without overloading the AC power source.<\/p>\n\n\n\n
