DELING Emergency Lighting Power Supply RKP220-12F-30 is a dedicated elevator emergency power unit. When the main elevator power fails, it automatically switches to its built-in battery to provide a stable 12V power supply for emergency lighting and intercom devices. This ensures that trapped passengers can see their surroundings in the dark and use communication devices to call for help, enhancing passenger safety and emergency response efficiency. Please contact customer service for more information.
