HLF3000-D48 3KW High-Reliability DC/DC Converter for Marine & Industrial Applications
Overview
The HLF3000-D48 is a robust, 3KW DC/DC power converter module engineered for demanding environments where reliability is non-negotiable. With a focus on marine electrification and versatile industrial use, it efficiently converts a wide-range high-voltage DC input (200–950VDC) into a stable 48VDC output – the emerging standard for onboard auxiliary systems and industrial equipment. Available in both enclosed (IP67) and open-frame versions, it combines ultra-high efficiency, comprehensive protection, and automotive-grade durability to power critical systems across multiple sectors.
Key Features
Ultra-High Efficiency: ≥96% full-load efficiency minimizes energy waste and thermal stress, crucial for energy-sensitive and thermally constrained applications.
Wide Input Compatibility: 200‑950VDC input range supports various high-voltage battery platforms from EVs, hybrid systems, and marine battery banks.
Stable 48V Industry-Standard Output: Provides a clean, stable 48VDC bus, ideal for powering modern marine electronics, industrial controllers, communication gear, and servo drives.
Marine & Industrial Toughness:
