    FAQ

    Q1: What battery voltages can this DC‑DC step‑down converter work with?

    This converter accepts a wide 20‑90V DC input and runs optimally with 24V, 36V, 48V, 60V and 72V batteries, it is suitable for electric vehicles, forklifts, RV energy storage and off‑grid solar systems to supply stable 12V power for lights, cameras, sensors and other 12‑volt DC loads.

    Q2: Do I need to fit an extra cooling fan for this buck converter?

    This unit relies on its ribbed aluminum housing for passive heat dissipation and does not require an external cooling fan under rated load, yet you must not place it in fully sealed air‑tight enclosures and leave adequate surrounding airflow so the heat‑sink shell can dissipate heat normally to prevent over‑heating faults.
