The elevator emergency 3P main board TD-ZB-02 is the core control unit of the elevator emergency system. In the event of an AC power outage or a malfunction in the elevator control system that leaves the car stalled in the shaft, this main board rapidly initiates the emergency protocol. It automatically disconnects the original control system, assumes control of the elevator, supplies AC power, and drives the car smoothly to the nearest floor. It then automatically opens the doors to allow trapped passengers to safely evacuate. This ensures a secure and efficient emergency rescue process.
