This 48V 30A charger (rated power approximately 1440W) is primarily designed for devices/battery packs with a nominal voltage of 48V and matching capacity (at a charging rate of 0.1C to 0.2C).  The following are specific application scenarios, presented clearly for easy understanding: I. Core Compatible Devices/Batteries (Key Points)1. 48V Lead-Acid/Lithium Battery Packs (Mainstream Compatibility)• Lead-acid batteries: 48V (4 x 12V in series), capacity 150AH-300AH (30A corresponds to 0.1C-0.2C charging rate), such as 48V 200AH, 48V 250AH lead-acid batteries (commonly used in energy storage and backup power);• Lithium batteries (lithium iron phosphate): 48V (16 series, actual nominal 51.2V), capacity 150AH-300AH, requires confirmation of charger cut-off voltage compatibility (strictly forbidden to charge lithium batteries with a...

In industrial power supplies, LED drivers, communication base stations, and other outdoor equipment, we often see switching power supplies that are completely "potted"—the entire circuit board is completely encased in a layer of transparent or gray resin. This seemingly ordinary resin is actually the "invisible armor" of the switching power supply, providing five core functions to ensure its long-term stable operation in harsh environments. I. Waterproof and Moisture-proof – "Invisible Waterproof Casing"The primary function of potting is waterproofing and moisture protection. The potting compound (mostly silicone or epoxy resin) forms a dense, non-porous barrier after curing, effectively blocking water, salt spray, acids, alkalis, and other corrosive media. This allows the power supply to operate reliably in high-humidity, outdoor, and salt-spray environments (I...
