Patent No. 10-1315827 (Elevator main power power saving device)
Standby power saving device
Standby Power Reduction Elevator
What is a standby power reduction device?
It is a device that reduces the economic loss by preventing unnecessary power loss by converting the elevator to standby power mode during the operation standby time waiting for a passenger’s call and cutting off continuous power supply to control devices and inverters.
Elevator waiting time is 3 times the actual operating time
