Adjustable Buck Converter 5A 75W with Voltmeter

Free shipping · 6–12 days · tracking

Adjustable buck converter (~5A / 75W class) with digital voltmeter — higher-current DC rails for LED strips, motors, and hungry bench fixtures when a 3A module is not enough.

Repair / DIY power workhorse: dial the output under a safe test load, watch the display, then feed the job. Kit includes heat sink and mounting hardware.

Features

- XL4015-class adjustable step-down with onboard digital voltmeter

- About 5A / 75W class (use the heat sink; derate if hot)

- Screw terminals IN / OUT; multi-turn trimmers for precise set

- USB-A tap on board for light 5V side loads (confirm wiring on your unit)

- Includes aluminum heat sink + brass standoffs / nuts for clean mounting

How to use

- Mount the heat sink, wire IN+ / IN− correctly, then set Vout with a light load first

- Read the display (or a multimeter) while trimming to the target voltage

- Ramp current gradually; keep airflow on the sink near the 5A end

- DC input only — never connect AC mains to this module

Typical jobs: LED strip / lamp rails, motor drivers, higher-load bench PSU taps, repair-fixture power when 3A bucks run out of headroom.
