VELLEMAN K7203 Adjustable 3-30V 3A Regulated Power Supply Kit

The VELLEMAN K7203 3-30V / 3A Power Supply Kit is a high-performance regulated DC power supply designed for powering electronic projects, laboratory equipment, development boards, and DIY circuits. Offering a fully adjustable 3V to 30V DC output with a maximum current capacity of 3A, this versatile kit is ideal for hobbyists, technicians, educators, and electronics professionals who require a stable and reliable power source.

Designed as both a permanent bench power supply and an auxiliary supply for a wide range of electronic applications, the K7203 is compatible with most Velleman kits and other electronic circuits requiring a regulated DC voltage. Its low 0.5mV ripple voltage provides exceptionally clean power, making it suitable for sensitive analogue and digital electronics where voltage stability is essential.

The circuit incorporates comprehensive protection features, including short-circuit protection and overload protection, helping to safeguard both the power supply and connected equipment during operation. This makes the unit suitable for continuous use in workshops, laboratories, educational environments, and repair benches.

The output voltage is adjustable using the onboard trimmer. For applications requiring frequent voltage changes, the trimmer can easily be replaced with an external potentiometer, converting the unit into a convenient variable bench power supply for testing and development work.

The K7203 accepts an AC input between 9V and 30V, depending on the required output voltage. A suitable transformer is required but is not included, allowing users to select the transformer best suited to their application. A heatsink is supplied with the kit to ensure efficient cooling and reliable operation under higher load conditions.

With its compact 130 × 91 × 50mm design, the completed power supply can be installed into a custom enclosure or integrated into larger electronic systems with ease.

Supplied as a self-assembly kit, the VELLEMAN K7203 offers an enjoyable electronics project while delivering a dependable adjustable power source suitable for countless electronic applications.

Whether you're powering prototypes, testing circuits, repairing electronic equipment, or building your own laboratory bench supply, the K7203 provides accurate, stable, and protected DC power for demanding applications.
