The AC70S special drive for construction elevators is a drive specially designed for the transformation of old elevators with a position stop function. It integrates a frequency converter, brake module, and status indicator. It is convenient for on-site maintenance of equipment and reduces the cost of construction elevator frequency conversion transformation.

Product Advantages：
1. Safe and reliable: The special brake logic control function, through the release frequency and the release current colleague to reach the brake, to ensure its safety and reliability.
2. High performance-price ratio: Compared with a complete set of inverter cabinets, the price is cheaper and the performance is equivalent.
3. Humanized design: No need to change the inverter parameters, as long as the wires are correctly connected, it can operate normally after turning on the machine.
4. The transformation is simple: no need to add deceleration limit devices, no replacement of the operating table; accurate landing can be achieved at any speed.
5. Convenient maintenance: The keyboard operator can display upper and lower limit, ascending and descending signals, which is convenient for system maintenance.
