Voltage Regulator Low Speed Automatic Generator Voltage Regulator 100-264VAC 1. SMT Technology: AS440 is a half wave phase controlled AVR type thyristor, which is part of the brushless generator excitation system. The design uses surface mount technology (SMT) to achieve a high degree of functional integration in the small size of the AVR. 2. Low speed protection: the frequency measurement circuit continuously monitors the generator output and provides low speed protection to the excitation system by proportionally reducing the output voltage below the set threshold. Manual adjustment is provided for the factory oacute point at low frequency roll down (UFRO). This can be easily changed to 50 or 60Hz in the live push link selection. 3. Use of electrical details: By using efficient electrical conductors in the AVR power circuit, the positive voltage is ensured from the residual level. The power and voltage sensing circuits have separate terminals which allow excitation power to be obtained directly from the stator winding of the primary application or from the auxiliary winding if a continuous short circuit is required. 4. Control details: based on this testing voltage, the AVR controls the power fed to the exciter magnetic field, thereby controlling the main magnetic field to keep the motor output voltage within a certain limit. 5. ABS material: Made of premium ABS material, this board is wear-resistant and impact-resistant, ensures long service life and durability.
