Power Amplifier
DXACP series power amplifiers
The power amplifier is specially designed for the supporting use of the vibration exciter, which can provide a stable and adjustable excitation current for the vibration exciter.
Under the action of the exciting current, the exciter generates an exciting force on the tested component corresponding to its exciting current. The magnitude and phase of this force are only related to the excitation current and the characteristics of the exciter itself, and have nothing to do with the component being tested.
This series of power amplifiers are linear power amplifiers with stable performance, strong protection functions, simple and clear operation, no shock when starting up, no pollution to the environment, and safe and reliable use. In addition, this series of power amplifiers have better adaptability. Although they are designed for vibration exciters, they are also suitable for loads whose impedance is basically matched. In particular, the DXACPS series power amplifiers have the characteristics of one machine and multiple devices, and they can also be used as signal sources and frequency meters, which are very popular among users.
