Product Description

Power Amplifier for Vibration Test Table

A power amplifier is a crucial component in a vibration test system, responsible for amplifying the control signal from the vibration controller to drive the vibration shaker. It converts a low-power electrical signal into a higher-power signal needed to move the shaker and generate the desired vibration.

Role of the Power Amplifier

The vibration controller generates a small analog signal that specifies the frequency and amplitude of the vibration. This signal is not powerful enough to directly drive the shaker. The power amplifier takes this signal and amplifies it to a level that can control the shaker's movement.

Amplification Process

The power amplifier takes the controller's signal and transforms it into a higher-voltage, higher-current signal. This higher-power signal is then used to drive the shaker's actuator, causing it to move and generate the vibration.

Types of Power Amplifiers

Different types of power amplifiers are used in vibration testing, including linear and switching amplifiers. The specific type used depends on the size and type of shaker, with some systems using matched amplifiers.

Key Features

High efficiency: Minimizes energy consumption and heat generation
Wide frequency response: Accurately reproduces the desired vibration frequencies
Low harmonic distortion: Ensures clean vibration waveforms
Safety features: Includes over-current and over-temperature protection

Importance in the System

The power amplifier is a critical link in the control loop of a vibration test system. Without it, the control loop would essentially stop at the controller's output, and the desired vibration levels could not be achieved.
