It adopts full SMT surface mount technology to realize high integration in a tiny module. High-quality semiconductors are used in power circuits to realize automatic voltage build-up only relying on generator residual magnetism. Separate terminals are designed for voltage sensing and excitation power. It supports power intake from main stator winding; auxiliary winding connection is optional if excellent continuous short-circuit resistance is required. Connected with stator and excitation windings to form closed-loop control, the voltage regulation accuracy can reach ±1%.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch2\u003e2.
