HAC High-Precision Active Vibration Isolator
HAC is the core control unit of an active vibration isolation system. It uses sensors to acquire vibration data in real time and calculates opposing compensation signals to cancel low-frequency vibration. Its multichannel interface design supports different types of active vibration isolation actuators and compensates for the limited low-frequency suppression of passive isolation. It is commonly used for vibration control in demanding equipment such as semiconductor inspection and precision microscopy systems. The HAC high-precision active vibration isolation controller is the core control device of an active vibration isolation system, primarily addressing the limited suppression of low-frequency vibration by passive isolation devices. External multiaxis vibration sensors can be connected to acquire weak horizontal and vertical ground vibration signals in real time. A dedicated built-in control algorithm performs high-speed calculations and outputs opposing drive signals to the isolation actuators, generating compensation forces that cancel vibration disturbances and provide dynamic active vibration isolation. The equipment uses a rugged industrial enclosure with good heat dissipation and stable operation. The panel provides multiple groups of standardized input and output interfaces for connection to active vibration isolation springs and a supervisory control system. Isolation parameters can be adjusted flexibly according to the on-site load and vibration conditions, facilitating commissioning and status monitoring. The product supports semiconductor inspection, electron microscopy, laser interferometry and ultraprecision measuring instruments, providing a low-vibration operating base for high-end precision equipment. It is commonly used in laboratories and intelligent manufacturing production lines.
