The role of elevator power failure emergency device

Automatic operation

When the elevator is in a dormant state during normal operation, and the elevator cannot work normally due to power failure, phase shortage and other abnormal situations, the emergency device will automatically start to work.

Intelligent identification of elevator light load direction

The intelligent main board of the machine intelligently recognizes the direction of light load when, for example, there are many people in the car and the weight of the car is greater than that of the counterweight, the elevator will run downward to open the door at the level by gravity, and, for example, if there are few people in the car and the weight of the car is lighter than that of the counterweight, the elevator will run upward to open the door at the level by gravity.

Low power consumption and long life

Because of intelligent direction recognition, relative battery loss is reduced, using specially designed trickle charge/discharge circuit to charge/discharge the battery, overcoming the self-discharge characteristics of the secondary battery, no need for human charging/discharging the battery and other maintenance, which greatly improves the life of the battery.

Stable operation and strong security

Because the control conversion between the device and the power supply all static point isolation, to ensure the normal operation of the elevator and the emergency process of signal acquisition, the safe operation of the rescue process, the device will not run in the event of a power failure, switched by the relay to the blackout emergency device, reads the second power supply.
