Brushless Generator AVR AC Automatic Voltage Regulator R448 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection to ensure safe, reliable control of the generator. Positive voltage builds up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed-loop control of the output voltage with load regulations of +/- 1.5%
|Voltage||95-480VAC, 3 phase|
|MAGNETIC FIELD OUTPUT|
|Voltage||Max 160VDC at 120VAC input|
|PRESSURE REGULATING ACCURACY||<+/0.05%RMS with 4% engine governing|
Load Adjustment Module (LAM):
On load impact, the rotation speed of the generator set decreases. When it passes below the preset frequency threshold, the LAM causes the voltage to drop by approximately 15% and consequently, the amount of active load applied is reduced by approximately 25% until the speed reaches it's rated value again
