Product Overview
OverviewThe Stamford AS540 Automatic Voltage Regulator (AVR) is a precision-engineered voltage control device designed to maintain consistent electrical output in generator systems. Manufactured exclusively in the United Kingdom by Stamford, a world-leading name in power generation equipment, the AS540 AVR ensures your generator delivers stable, reliable voltage regardless of load fluctuations or engine speed variations. This OEM component is critical for protecting sensitive electrical equipment, preventing damage from voltage spikes or drops, and ensuring optimal performance across industrial, commercial, and standby power applications. When your generator's voltage output becomes erratic or unstable, the AS540 AVR is often the solution that restores proper function and extends the service life of your entire power system.As an essential part of your generator's control system, the AS540 voltage regulator continuously monitors output voltage and makes real-time adjustments to the alternator's excitation current. This automatic regulation process happens instantly, compensating for changing loads, temperature variations, and operational conditions to deliver steady power quality. Whether you're operating construction equipment, providing backup power for critical facilities, running agricultural operations, or maintaining telecommunications infrastructure, the Stamford AS540 AVR provides the voltage stability necessary for safe, efficient operation. This genuine Stamford part carries the A054P369 designation and represents authentic OEM quality that meets or exceeds all original equipment specifications.Key SpecificationsSpecificationValueModel NumberAS540 (A054P369)ManufacturerStamford (Made in UK)Input Voltage Range85-264 VACRegulation Accuracy±0.5% steady stateOutput Voltage190-264 VAC nominalFrequency Range50/60 HzOperating Temperature-40°C to +70°CResponse TimeLess than 100 millisecondsBuild QualityConformal coated PCB for harsh environmentsMounting TypeStanda
