What battery types are supported?
Mainly 12V/24V lead‑acid automotive, motorcycle, and marine batteries, as well as 12–120V lead‑acid battery packs for industrial backup systems.
Does the charger stop automatically when full?
Yes. The automatic mode detects full‑charge conditions and switches to floating‑charge or cuts off output, preventing overcharging and gas emission.
What current range is available?
Rated maximum output currents from 10A to 100A, with specific models for different battery sizes (e.g., 10A–20A for small vehicles, 40A–100A for larger industrial systems).
Is it suitable for long‑term industrial use?
Yes. The fan‑cooled design, multiple protections, and wide operating‑temperature range make it suitable for industrial plants, marine applications, and backup‑power stations.
Can input voltage be customized?
Standard input is 220–240 VAC, 50–60 Hz, but other voltages (e.g., 110 VAC) can be customized on request.
