efficiency operation with up to 97 percent efficiency, enabling effective voltage reduction with minimal heat. Broad input and adjustable output: a DCDC stepdown converter module that accepts input from 6.5 to 60 V and provides an adjustable output from 1.25 to 30 V, with a maximum current of 10 A. Compatible applications: suitable for lithium or lead batteries, low voltage system power supplies, and charging of 6 V, 12 V, 14 V, and 24 V batteries, as well as serving as a regulated power supply. Easy connections: input and output terminals use screw terminals for convenient, reliable wiring. Use scenarios: Charging battery packs from lithium or leadacid chemistries (6 V / 12 V / 14 V / 24 V) using the adjustable output. Providing a regulated lowvoltage supply for electronics or embedded systems from a higher voltage source (for example from automotive or solar sources) within the 1.25 to 30 V range. Supplying a stable voltage for DIY projects or test benches that require adjustable output from a wide input range (6.5 to 60 V).
