Portable adjustable power supply

The Adafruit KJS-1509 is a compact adjustable power supply that delivers 3V to 24V DC at up to 2 Amp. It is built for makers, students and engineers who need a portable bench-top style source for robotics or electronics prototyping. The unit includes a 2-prong mains plug and a 2.1mm barrel jack for immediate connection to development boards or LED strips.

Flexible voltage selection for prototyping

A front-panel potentiometer and 7-segment digital display let you dial the output to 3V, 5V, 6V, 9V, 12V or 24V to match the device under test. Six mounting holes allow a permanent bench installation while the lightweight chassis remains easy to move between workstations. The 2.1mm and 5.5mm DC connectors cover common barrel-jack sizes without extra adapters.

Efficient linear regulation in normal use

The supply runs from standard AC mains and maintains a stable DC output across the full adjustment range with minimal ripple. A built-in LED display draws negligible current and the enclosure stays cool during typical loads. No external cooling or additional power components are required for operation within the rated 2 Amp limit.

Kysymyksiä tästä tuotteesta

What is the maximum current the KJS-1509 can deliver continuously at 24 V?

The supply is rated for 2 A across the full 3 V to 24 V range, so the 24 V setting is limited to 2 A continuous output.

Does the unit use a fan or run silently during extended bench sessions?

No fan is mentioned in the specifications, indicating passive cooling and silent operation during all-day use.

Which barrel-jack size must my project cable match to connect directly?

The output uses a 2.1 mm centre-positive barrel jack, so your cable needs a matching 2.1 mm plug.
