VFD (Variable Frequency Drive) is a crucial component in industrial automation, widely used to control the speed and torque of AC motors by varying the input frequency and voltage. This category includes a range of VFDs designed for different applications, such as pump control, conveyor systems, HVAC, and CNC machinery. Key features often include energy efficiency, precise speed regulation, overload protection, and compatibility with various motor types. Products in this category may also support advanced functions like PID control, braking resistors, and communication protocols (e.g., Modbus, PROFIBUS). Common models range from compact low-power drives to high-performance units for heavy-duty industrial use.
