AVI Controller

Each antivibration setup comes with an AVI controller box. The AVI Series controllers provide the power to drive the isolation modules. They control the activation/deactivation of active vibration isolation and provide feedback on the overload levels of any of the isolation modules connected. A different controller model is required depending on the number of isolators in the system. If necessary, several controller units can be combined into one antivibration setup.
