PRODUCT CENTERGKGR Series General Mining Medium Voltage Soft Starter
Multiple security protection(up to 9)
Compatible with various installation environments
High protection level(for cabinet)：IP54
Flexible starting modes
The GKGR series mine general medium-voltage soft start control cabinet adopts DSP control technology. During startup, it detects current and power factor, controls output voltage, and reduces starting current to ensure smooth motor startup. Upon stopping, it controls output voltage and gradually decreases running current for a smooth motor stop. This effectively reduces the starting impact current of the motor, minimizes the impact on the power grid, and also reduces the mechanical impact force on the mechanical load devices connected to the motor, extending the equipment's lifespan and lowering the later operational and maintenance costs. The product also features protection functions against overload, three-phase imbalance, phase loss, undervoltage, starting overcurrent, and starting timeout faults. It is mainly suitable for the control and protection of starting, running, and stopping large power asynchronous or synchronous motors.
