HFVA series power amplifier is designed for inductive (or capacitive) load. It is designed with the wisdom of many professors of Nanjing University of Aeronautics and Astronautics. This series of power amplifiers are linear power amplifiers, which have the characteristics of small interference, good linearity, small distortion, high stability, wide frequency range, etc. At the same time, it has the advantages of beautiful shape, simple panel and easy operation. It is very suitable for the research of ultrasonic motor technology, the vibration experiment of piezoelectric ceramics (crystal) and the detection experiment of cavity flow excitation.

        ■ It is used to excite capacitive loads such as piezoelectric ceramics, piezoelectric crystals, and inductive loads such as coils. It can be used for ultrasonic motor research and teaching experiments.
