About Power Amplifier

A vibration test system requires Power Amplifier to drive the shaker. The amplifier amplifies the signal from the vibration controller and sends it to the vibration generator. We have a wide range of lineups, from small to large, depending on the system.

Role of Power Amplifier Increase the signal from the controller, then send it to shaker. Controller signal Increased signal shaker Receives the signal and converts it to vibration excitation output
