HLF4K-D25-H800 – Lightweight 4kW Victor Replacement DC/DC Converter | 25V Adjustable
HLF4K-D25-H800 – 4kW Lightweight Airborne DC/DC Converter
Drop‑in Replacement for Victor Power Supplies | 25V Adjustable | Directly Powers 6S LiPo | ≥96% Efficiency
Overview
HLF4K-D25-H800 is a lightweight, high‑efficiency 4kW onboard DC/DC converter designed as a direct drop‑in replacement for Victor‑series power supplies. It offers superior power density, lower weight (just 1050g), and modern features at a competitive cost. Engineered for heavy‑duty tethered UAVs and 6S LiPo‑powered drones, it converts a 680–800 VDC input into an adjustable 25V output, providing up to 160A at 25V(4kW continuous). With ≥97% efficiency and CAN 2.0 monitoring, it ensures reliable operation in harsh flight environments. If you are currently using Victor 4kW power modules, the HLF4K-D25-H800 delivers equal or better performance with lighter weight, adjustable voltage, and enhanced thermal management.
Key Features – Why It Beats Victor
Lightweight Design – Weighs only 1050g – significantly less than equivalent Victor models, maximizing drone payload capacity.
Direct Victor Replacement – Same 680‑800V input, 25V output, and CAN communication – no airframe modification required.
Adjustable Output (25V ) – Set to 25V for 6S LiPo systems (nominal 25V). Victor units often lack this flexibility.
4kW Power Capability – 4kW continuous, up to 160A at 25V; delivers full rated power with ≥96% peak efficiency – lower heat than Victor.
Complete Protection Suite – Input UVP/OVP, output UVP/OVP/OCP/SCP, intelligent thermal derating, input fuse.
CAN 2.0 Communication – Real‑time monitoring and control; fully compatible with Victor’s CAN protocol.
Rugged Mechanical Design – Rubber damping pads, compact 187×95×70 mm footprint, forced air cooling recommended for sustained full load.
Wide Temperature Range – -20°C to +85°C operating, suitable for outdoor and airborne missions.
