KE300A-06 Series Construction Elevator Special Inverter
KE300A-06 elevator inverter, specially designed for industrial applications such as tower cranes, construction ladders, and hoisting. Compared with traditional elevator drive control systems, the program has been adapted to the application characteristics of elevators Professional design of brake logic timing control function, advanced current limiting technology, and hardware optimized design. The vector drive is combined with the lifting logic control to ensure the comfort and safety of the brake at the moment of opening. There is no "overshoot" phenomenon in the upward direction and no "weight loss" in the downward direction.
Features of KE300A-06 Series Construction Elevator Special Inverter
(1) Compared with traditional non-speed-adjustable elevators, it is more comfortable. It ensures the comfort and safety of the brake at the moment of opening. There is no "overshoot" phenomenon in the upward direction and no "weightlessness" in the downward direction.
(2) It can realize energy feedback, good braking effect, and can save a lot of energy.
(3) High torque at low frequency.
(4) The frequency conversion speed regulation system has perfect safety protection function. Such as under-voltage, over-voltage, over-torque, over-current protection, etc., to ensure the reliability and safety of the entire electronic control system.
(5)Since the system is a low-speed brake, the brake has a relatively small rotational friction, which greatly extends the service life of the brake.
