The AKS620 Mining Low Voltage Soft Starter is designed for coal mines containing explosive gas (A-burning) and coal dust environments. It provides remote control of soft starting, stopping, and reversing operations for mining explosion-proof three-phase squirrel-cage asynchronous motors, offering comprehensive protection for the motor and its wiring.
Key advantages include small starting current, balanced and reliable starting speed, vibration-free startup process, and minimal impact on the power grid. The "S" curve starting profile can be adjusted according to actual working conditions, making it particularly suitable for heavy load equipment such as underground scraper conveyors, belt conveyors, and combined coal mining machines.
