Features:
1R180 is an allfirmstate automatic voltage regulator (AVR) used to excite a brushless alternator powered by a permanent magnet (PMG) exciter or auxiliary winding 2AC generator voltage between the VW phases is sampled, processed, and converted into a DC value. This signal is compared with a reference value generated internally according to the voltage setting 3Controls the alternator width modulation (PWM) IGBT circuit to adjust the excitation current to provide good dynamic/transient response 4The 1A and 5A signals from the U-phase droop current transformer are required to provide voltage droop, allowing the alternator to operate in parallel 5R180 has an accessory input, can be used as a remote potentiometer terminal when connected to a 1 K potentiometer or when 4.5V DC is required to change the terminal voltage
