In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals. \u003cbr\u003e\u003cbr\u003ePositive voltage build-up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. \u003cbr\u003e\u003cbr\u003eThe AVR is linked with the main stator windings and the exciter field windings to provide closed-loop control of the output voltage with load regulation of +\/-1.0%. In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for the load, speed, temperature, and power factor of the generator.\u003c\/p\u003e\n\u003cp\u003eSpecification(s)\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand Name: Northline Parts\u003c\/li\u003e\n\u003cli\u003eINPUT: Voltage: Jumper selectable 95-132V ac or 190-264V ac, Frequency: 50-60 Hz nominal, Phase: 1\u003c\/li\u003e\n\u003cli\u003eOUTPUT: Voltage: Max 90V dc at 207V ac input, Current: Continuous 4 A dc, Intermittent 6 A for 10 secs, Resistance: 15 ohms minimum\u003c\/li\u003e\n\u003cli\u003eRegulation: +\/-1.0%\u003c\/li\u003e\n\u003cli\u003eThermal Drift: 0.05% per deg.
