Excitation Regualtor
Product Description
SMER MCU based excitation regulator is applicable to small and medium-sized synchronous generator excitation system, for stand alone and connecting to grid operations. This excitation regulator has simple structure, powerful function, east to use and reliable.
SMER excitation regulator is applicable for to the rectifier circuit with 1 to 6 SCR, including single phase half wave thyristor rectifier circuit, single phase half controlled bridge rectifier circuit, three phase half controlled bridge rectifier circuit, three phase full controlled bridge rectifier circuit.
Funcation and Hightlight
(1) Colorful LCD touch screen, with operation prompt, event and alarm display.It is a user friendly device with minimum manual operation.
(2) It is able to built-up with low setting voltage.
(3) Auto tracing grid voltage while built-up voltage, auto switching control mode to Cos(A) control, so to minimize manual operations.
(4) Easy to construct redundant excitation system.
