A800L Series Elevator Frequency Inverter

 A800L open-loop frequency inverter (VFD) for elevators is a device specifically designed for elevator control. As a high-end product among small and medium power rating frequency inverters, it aims to improve the efficiency of elevators, ensure smooth operation, and extend equipment lifespan. A800L frequency inverter adopts open-loop control mode, combined with PLC or microcomputer control, demonstrating the superiority of contactless control, including simplified circuit, flexible control, reliable operation, convenient maintenance and fault monitoring.

The control of the A800L elevator open-loop frequency inverter is S-shaped, which means that the acceleration during starting and stopping is relatively gentle, while the acceleration during the intermediate process is relatively fast. This design is mainly aimed at providing ride comfort and energy-saving effects. It directly controls the output frequency and voltage to drive the motor, without additional energy consumption, so it has higher efficiency compared to other speed control methods (such as series resistance speed control).
