Adjustable 3V–24V 144W Power Supply

This adjustable switching supply accepts AC 100–240 V input and delivers DC output from 3 V to 24 V at up to 6 A, with a maximum rating of 144 W. The built-in rotary knob selects the required voltage and includes an off position so the unit can be powered down without unplugging. A front LED shows the set voltage in real time.

14 Tips, Polarity Cable and Test Leads

The package includes the standard 5.5 × 2.1 mm tip plus 14 additional connectors covering Micro-USB, Type-C, DC terminal, 6.4 × 4.0 mm, 5.5 × 2.5 mm, 5.0 × 3.0 mm, 5.0 × 2.5 mm, 6.3 × 3.0 mm, 5.5 × 1.7 mm, 4.8 × 1.7 mm, 4.0 × 1.7 mm, 3.5 × 1.35 mm, 3.0 × 1.1 mm and 2.5 × 0.7 mm. A 17 cm reverse-polarity converter cable swaps centre-positive to centre-negative when needed. Three PVC-insulated test leads with nickel-plated alligator clips are also supplied for bench use.

Engineers, Hobbyists and Service Technicians

The wide voltage range and large tip assortment suit prototyping, repair work and powering legacy hardware that uses barrel, USB or terminal connections. Users needing more than 6 A or voltages above 24 V should look at higher-capacity units. The Type-C and Micro-USB tips are intended for low-power devices below 12 V, so they will not support high-current USB-PD applications.

Questions about this item

Will the 14 included tips and test leads need replacing after regular use?

The package supplies 14 interchangeable DC tips plus a reverse-polarity cable and three PVC-insulated test leads with nickel-plated alligator clips; spare tips are not included, so any worn or lost connectors would need to be sourced separately.

At what output level does the 6 A current limit engage?

The unit delivers a maximum of 6 A across the 3 V to 24 V range, so the current limit activates at 6 A regardless of the selected voltage.

How much heat or fan noise should I expect when running the supply at 144 W continuously?

The adapter uses a switching design with no fan mentioned in the specifications; thermal performance under sustained 144 W load is not described in the supplied data.
