Product description:

   This product is used in 30 - 3000KW , the commonly used excitation current of less than 15A brushless generator sets . Control the size of the excitation current to regulate the stability of the generator output voltage , and the ability to slow three-phase voltage to establish . Output 15A of the maximum excitation
Establish voltage : the voltage will automatically establish the speed is greater than 25Hz , can the three-stage slow to establish the voltage to effectively prevent overvoltage .
