Shenzhen Eltrum Electronic Co., Ltd. specializes in the R&D and volume manufacturing of high-performance DC-DC boost converters and step-up regulators. With over a decade of dedicated power electronics innovation, our engineering team delivers precision step-up conversion modules that convert lower DC supply voltages (such as 12V or 24V vehicle and solar battery banks) up to elevated regulated rails including 15V, 19V, 24V, 28V, 36V, and 48V DC.
Our converters are trusted globally across automotive modification, golf carts, marine battery setups, solar photovoltaic off-grid systems, telecom power backups, and industrial robotics. Each unit is encapsulated in an aluminum alloy shell with pure thermal silicon resin potting, achieving true IP68 waterproof, dustproof, and anti-shock performance in rigorous commercial and industrial working conditions.
Smart internal circuitry safeguards both upstream battery banks and sensitive downstream electronics.
OEM / ODM Flexibility
