HEA Series Power Amplifiers
HEA series power amplifiers are specially designed for the use of exciter, which can provide a stable and adjustable excitation current for the exciter.Under the action of the excitation current, the exciter generates an excitation force on the tested component that corresponds to the excitation current, and the magnitude and phase of this force are only related to the excitation current and the characteristics of the exciter itself, but which is independent of the tested component.
HEA series linear power amplifiers has below advantages:
stable performance, strong protection function, easy to operation, no impulse during startup, no pollution to the environment, safe and reliable use. In addition, HEA series linear power amplifiers have good adaptability, which is suitable for the impedance of its basic matching load. It is widely used in excitation of inductive loads such as electromagnets and Helmholtz coils.
