HBK3 Master ControllerDetailed product description：

The HBK3 master controller is mainly used for various secondary circuits with AC 50Hz (60Hz), rated voltage of 380V (440V) and below, including sequential, 1-5 speed regulation, braking, linkage, and transfer control operations.

Structural characteristics:
The HBK3 master controller integrates advanced technologies at home and abroad, adopts a modular combination structure, is designed reasonably, has a simple structure, and has a high degree of standardization. The transmission part is preferably made of special nylon material to achieve lifelong maintenance capability. And it is easy to operate, with a clear hand feel and clear gear positions. The operating mechanism is equipped with zero position self resetting and self locking devices, all of which use Schneider contacts, ensuring safe and reliable operation and long service life. Wiring, installation, and maintenance are all very convenient, and each mechanism can be equipped with potentiometers and encoders, making it easy to combine functions. Suitable for control operations of various types of large and medium lifting equipment.
