VELLEMAN K1823 Adjustable Regulated Power Supply Kit 1.2V-35V 1.5A

The VELLEMAN K1823 Regulated Power Supply Kit is a compact, adjustable DC power supply designed to provide a stable and reliable output voltage for a wide variety of electronic projects, laboratory applications, and DIY circuits. Based on the highly popular LM317 adjustable voltage regulator, this kit delivers excellent voltage regulation, low ripple, and dependable performance compared to conventional fixed-voltage regulators.

The output voltage is continuously adjustable from 1.2V to 35V DC, making the K1823 suitable for powering prototype circuits, development boards, test equipment, small motors, sensors, and numerous electronic devices. With a maximum output current of 1.5A, the power supply offers sufficient capacity for many low- to medium-power applications.

The LM317 regulator incorporates built-in current limiting and thermal overload protection, helping safeguard both the regulator and connected equipment from damage due to excessive current or overheating. When used with a suitable heatsink (not supplied), the regulator can safely dissipate up to 15W, ensuring reliable operation under higher load conditions.

Designed for flexibility, the module accepts a maximum 40V DC input and provides excellent ripple rejection, resulting in a clean, stable output that is ideal for sensitive electronic circuits. Its compact 52 × 30mm PCB allows easy integration into bench power supplies, custom enclosures, educational projects, and portable equipment.

Supplied as a self-assembly kit, the VELLEMAN K1823 is an excellent choice for students, hobbyists, technicians, and engineers looking for an affordable adjustable regulated power supply with professional-level performance.
