This will cause the service (or type of unit) associated with the timer unit to start every 11 minutes. But only if the service isn't still activated as I understand. OnActiveSec=11min will start the service once 11 minutes after the timer unit itself is started. There's also OnUnitInactiveSec where the service is started 11 minutes after it has stopped. This may be useful if your service may need more than 11 minutes until it exits.
In the man page it is recommended to combine OnUnitActiveSec with onBootSec to start the service once after boot and in regular intervals from then on. However there's one difference between these relative triggers and OnCalendar: you can only use Persistent= in combination with OnCalendar. This means that if your timer elapses in 5 minutes and you suspend your machine for an hour or so, after resume it still elapses in 5 minutes.
