Which provides smoother operation and power outage service?

Explanation:
Battery backup power gives the escalator or moving walk a source of energy to run when the main electrical supply is lost, so it can continue to operate to a safe stopping point or provide limited service during an outage. That stored energy also helps keep the drive electronics supplied during minor voltage dips, allowing the controller to apply a controlled, smooth-start and maintain steady speed rather than surging or stalling. The other options relate to physical components or safety features that don’t provide power or improve drive smoothness during outages.
