Elevator ARD Emergency Power Automatic Rescue Device Elevator ARD
Emergency auto rescue device of elevator is the safety device designed for the optimization of modern elevator. Ard monitoring the elevator power supply all time, when the elevator power supply system failure (power off, stop-phase) , it start work immediately and output power for elevator emergency operation. Then elevator run to the nearest door zone and open the door to rescue the passenger, to avoid the consequences caused by the elevator.
Features of the elevator power supply:
1. The device battery utilization rate is high and low power consumption and high inverter efficiency.
2. High anti-interference. The device has input and output EMI filter to meet the EMC test.
3. Low requirements for elevator system configuration. The output of the equipment can provide enough power for all elevators to run slowly.
4. high efficiency and multi AD sampling make the output voltage regulating fast and output voltage stability.
5. High security, The equipment adopts external wiring to avoid the internal high voltage device.
6. Overload restart,When the device detects an overload, it will start again, and give overload signal to facilitate the adjustment of the direction of the elevator.
