Máy tăng cường thử nghiệm rung động mô-đun Hiệu suất cao cho điều khiển máy rung

Power Amplifier for Vibration Test Table In vibration testing systems, the power amplifier supplies the power to drive the electrodynamic shaker. The vibration controller outputs a simple analog signal that describes the amplitude and frequency of the vibration profile in terms of a rapidly varying voltage. This voltage signal cannot drive the shaker, so the power amplifier converts it to a high-level actuator current that can. Without this device, the control loop would
