The control system

The control system of this series of dumb waiter are Microcomputer frequency modulation and voltage control,which change the elevator speed form single speed to infinitely variable speeds,so that the elevator can moved as the rated route to achieve better landing accuracy.Due to the adopt of VF technology,the running speed increase to 1.0m/s for the original 0.4m/s,by which it achieves higher efficiency and more convenient,more stable and more energy-saving.
