2 Phase Ard Systems

The 2-phase ARD (Automatic Rescue Device) system is indeed a critical safety feature in elevators. By ensuring the Elevator Controller is powered at its rated voltage, it guarantees that the rescue operations can be performed effectively during power outages or emergencies. In such situations, when the main power supply fails, the ARD system kicks in to provide the necessary power to the Elevator Controller. This enables it to execute controlled rescue procedures, including moving the elevator car to a safe position, opening doors, and facilitating the safe evacuation of passengers. This redundancy in power supply is essential for maintaining passenger safety and confidence in elevator systems.
