( Brand: Fairchild ), ( Part Type: Box Regulator )
The Fairchild 41-100 Box Regulator is a vintage electrical component that was once a staple in many electronic systems. This regulator, manufactured by the renowned Fairchild Semiconductor, is a mechanical voltage regulator designed to provide a stable output voltage, typically 6V DC, despite variations in the input voltage.
The Fairchild 41-100 Box Regulator is housed in a sturdy, all-metal enclosure, measuring approximately 3.5 inches in length, 2 inches in width, and 1 inch in height. The front of the regulator features a circular dial with a central needle, which indicates the output voltage. The dial is graduated in 0.5V increments from 0 to 7V, providing an easy and intuitive means of monitoring the regulator's output.
The regulator features two screw terminals for the input and output connections. The input terminal is marked with a ' ' symbol, indicating the positive input voltage, while the output terminal is marked with a '-' symbol, indicating the negative output voltage. The regulator is designed to operate with input voltages ranging from 9V to 30V DC, making it versatile for use in a variety of applications.
The Fairchild 41-100 Box Regulator operates on the principle of voltage regulation through the use of a series-wound transformer and a mechanical rheostat. The transformer steps down the input voltage to a lower voltage, which is then regulated by the rheostat to maintain a stable output voltage. The regulator's operation is largely self-contained, requiring no external power source or additional components for operation.
The Fairchild 41-100 Box Regulator is a reliable and robust component, making it an ideal choice for use in vintage or classic electronic systems. Its mechanical design allows for easy adjustment of the output voltage, and its sturdy construction ensures long-term reliability. Whether you're restoring a vintage radio, building a classic guitar amp, or simply looking for a unique and vintage component for your electronic projects, the Fairchild 41-100 Box Regulator is an excellent choice.
