HOW IT WORKS

The system supplies:

600 VDC for the VF drive

230 VAC for brakes, controller, and door operators

Real-time battery level monitoring from the controller

Energy regeneration: stores lift-generated energy for reuse

Low input to maintain charge

Compact 48V battery packs, low cost and easily replaceable

COMPLIANCE & SAFETY

EN 81-76:2025 introduces new inclusive evacuation modes:

Driver-Assisted Evacuation – A trained operator aids in evacuation

Automatic Evacuation – The lift functions autonomously in emergencies
Remote-Controlled Evacuation – A technician operates the lift remotely

These standards ensure inclusive, reliable evacuation in all building types  with direct implications for building design, fire strategy, and regulatory compliance. A LEIA BS EN 81-76:2025 guidance note can be read here: EN81-76.
