Description
The AVR SX440 Stamford Generator Voltage Regulator is a high-quality, field-proven automatic voltage controller, specifically designed for use with Stamford alternators and other compatible generator systems. Engineered for precision, safety, and long-term reliability, this AVR plays a vital role in regulating output voltage, maintaining power quality, and protecting both the generator and connected equipment.
Whether you're using a 15 kVA or a 200 kVA generator, the SX440 ensures consistent voltage output, even under fluctuating load conditions. This makes it a trusted component for a wide range of applications such as construction sites, hospitals, telecom towers, industrial plants, data centers, hotels, and agricultural setups. If your business relies on clean, uninterrupted electricity, the AVR SX440 offers performance you can depend on.
The dual excitation compatibility—with both shunt and PMG (Permanent Magnet Generator) systems—makes this AVR highly versatile. In PMG mode, it delivers enhanced voltage stability and allows the regulator to function independently of load fluctuations. This helps maintain consistent output during startup, short-circuit conditions, and rapid load changes—conditions where standard regulators might fail or falter.
A key benefit of the SX440 is its remote voltage sensing feature. This allows the AVR to sense voltage at the load end rather than at the alternator, making it capable of more accurate correction and better voltage control over long cable distances. This is critical in large facilities and installations where voltage drops across long runs are common.
The AVR includes built-in adjustment potentiometers for both output voltage and system stability, allowing technicians or users to fine-tune performance as per operational demands. The ±1% voltage regulation ensures your connected devices—like motors, lighting, panels, or IT equipment—receive stable power, thus reducing the chances of failure or downtime.
To protect both the generator and load, the SX440 is equipped with advanced thermal overload protection and under/over voltage shutoff capabilities. In case of abnormal operating conditions, the AVR will disconnect or limit voltage output, preventing damage to the system. This not only extends the lifespan of your generator but also minimizes maintenance costs.
