Power Amplifiers

We are offering power amplifiers.
The purpose of power amplifier is to provide power to the vibrator's armature coil. The power is in the form of voltage & current. In simple terms the velocity (armature speed) is proporational to voltage and force or acceleration is proporational to current. To achieve this function it amplifies the output signal of vibration controller/sine wave generator, sufficiently to drive the exciter to the desired vibration level. The d.c. Supply to create the static magnetic field is also built in.
