Radioshack LM317 Adjustable 9V Power Supply (AD444) - Versatile and Reliable Power Solution

The Radioshack LM317 Adjustable 9V Power Supply (AD444) is an essential tool for hobbyists, electronics enthusiasts, and DIY project builders, offering a high-quality and adjustable power solution for various electronic devices. This power supply unit, manufactured by Radioshack, is based on the widely used LM317 adjustable voltage regulator chip, ensuring accuracy and stability in voltage output.

The Radioshack AD444 power supply unit features an output voltage range of 1.2V to 15V, but when set at 15V and loaded with 1.6Ohms or less, it can deliver 9V DC, making it a perfect match for most electrified projects. Featuring a center-tap output, this power supply enables you to tap power at midpoint, providing additional flexibility for powering two-rail components or voltage-sharing applications.

The AD444 power supply includes several safety features like overvoltage, short-circuit, and thermal protection to safeguard the connected devices from potential damage. Its compact design, presenting dimensions of 1.2 inches (W) x 2.4 inches (L) x 1.2 inches (H) and a weight of 1 lb, makes it inconspicuous for smaller workspaces or field use. Additionally, there is a transformer isolation on the AD444, eliminating the need for an external transformer, and a grounded three-pronged AC cord, allowing the power supply to comply with the safety standards for operating in the US or Canada.

The power supply unit offers a continuously adjustable output voltage that can be set using two potentiometers located on the chassis. The voltage regulation is so accurate that even small adjustments can yield significant improvements in voltage readings of your sensitive components. Users can entirely bypass the regulation circuit with the AC bypass switch when manually adjusting components' voltage levels, achieving desired voltage levels more easily, and making it a perfect power solution for building or modifying specialized equipment.

For added convenience, the Radioshack LM317 AD444 power supply comes with a 3 ampere current limit and ships with a drawbridge connector, providing easy access to 12V and 5V voltages, perfect for powering an extensive range of accessories like relays, LED strips, and high-current applications. This feature-rich power adapter is a must-have accessory for electronics enthusiasts and hobbyists, offering a versatile and powerful power solution for their awe-inspiring projects.
