AKS620 Mining Low Voltage Soft Starter 1140V Soft Starter
Product Overview
The starter is suitable for coal mines containing explosive gas (A-burning) and coal dust, and is used for remote control of soft starting, stopping and reversing or stopping in place of the corresponding frequency and voltage of mining explosion-proof three-phase squirrel-cage asynchronous motors in normal operation to provide comprehensive protection for the motor and its wiring, and it has the advantages of small starting current, balanced and reliable starting speed, no vibration of the start-up process tape, and small impact on the power grid. The starting curve is "S" curve.
The starting curve is "S" curve, which can be adjusted according to the actual working conditions on the site, especially suitable for underground scraper conveyor, belt conveyor and joint coal mining machine and other heavy load equipment.
This curve can be adjusted according to the actual working conditions on site, especially suitable for soft starting of heavy load equipment such as underground scraper conveyor, belt conveyor and combined coal mining machine.
Product Key Features
Leakage lockout
Built-in leakage detection function, using additional: DC way to detect leakage, without the need for external leakage plug-in.
Bypass monitoring
Whether it is a direct start or soft start state, it plays a real-time monitoring function, more comprehensive protection of the motor.
Modularized design
Split modular design is more convenient for production, installation, dismantling and maintenance, and the scientific design of balancing principle realizes the purpose of simple and convenient operation.
Communication function
Standard configuration of communication components, support for customization, a variety of standard bus protocols, easy to realize group control technology, factory default Modbus-R Tu protocol.
