The AKS620 open type soft starter for mining is a high-tech product designed and manufactured independently by our company. This product complies with Q/AZ2058-2005 and MT/T943-2005 standards and represents an improvement over traditional explosion-proof and intrinsically safe vacuum electromagnetic starters by implementing soft starting and stopping functions.
This advanced system maximizes the elimination of mechanical and current shocks, significantly prolonging equipment service life. Its modular structure design is particularly suited for maintenance and operation in demanding environments.
The starter is suitable for AC 660V, 1140V voltage systems with rated current up to 400A, providing comprehensive protection for motors and wiring in explosive gas (A-burning) and coal dust environments found in coal mines.
- "S" curve starting: Adjustable starting profile suitable for heavy load equipment like underground scraper conveyors, belt conveyors, and combined coal mining machines
- Comprehensive protection: Includes short-circuit, over-voltage, under-voltage, overload, phase failure, and current imbalance protection
- Advanced monitoring: LCD display shows current, voltage, and various motor parameters
- Flexible control: Multiple run command input options including LCD keyboard, control terminal, and RS485 communication
- Modular design: Facilitates production, installation, and maintenance
