~ Rask Assembly of Power Amplifie and Servo Protector ~

The Pulse Width Modulation (PWM) power amplifier is designed with high efficiency, low noise, small size, and with characteristics much like a linear amplifier, but without high dissipation and bulk. It can reach maximum output levels for longer durations - with outstanding repeatability and unparalleled linearity. For all conditions, power device junctions are continuously monitored to ensure safe and reliable performance. It can be fully integrated into rack assemblies for single or multi-axis requirements

The 9363-PT3 Servo Protector is specially designed for vibration testing system. It comprises 6 analog meters respectively for input signal, temperature and output voltage and current of Power Amplifier, temperature of voice coil, and airflow of exhaust system to avoid potential abnormal conditions that affect the testing. It also features 10 abnormal digital indicator lamps in terms of over displacement, over current, abnormal temperature of voice coil and power amplifier, abnormal of exhaust system and N.TR/P.TR of power amplifier, and emergency stop.
