HLF6K-D50-H800 – Lightweight 6kW Victor Replacement DC/DC Converter | 50V/120A for Tethered Drones
HLF6K-D50-H800 – 6kW Lightweight Airborne DC/DC Converter
Drop‑in Replacement for Victor Power Supplies | 680‑800V Input → 50V / 120A Output | Optimized for 12S LiPo & Tethered Drones
Overview
HLF6K-D50-H800 is a lightweight, high‑efficiency 6kW onboard DC/DC converter designed as a direct drop‑in replacement for Victor‑series power supplies. It offers superior power density, lower weight, and modern features at a competitive cost. Engineered for heavy‑duty tethered UAVs and 12S LiPo‑powered drones, it efficiently converts a 680–800 VDC input into a stable 50 VDC output at 120 A (6kW continuous). With ≥97% efficiency and a compact, rugged design, it significantly reduces cable losses over long tether runs while providing unlimited flight endurance. If you are currently using Victor power modules, the HLF6K-D50-800 delivers equal or better performance with lighter weight, smaller footprint, and enhanced CAN integration.
Key Features – Why It Beats Victor
Lightweight Design – Weighs significantly less than equivalent Victor models (exact weight: contact sales), maximizing drone payload capacity and flight agility.
Direct Victor Replacement – Same 50V output, 120A capability, CAN communication, and mounting compatibility – no airframe modification required.
High‑Voltage Input (680‑800V) – Enables efficient long‑distance power transmission, reducing tether cable weight and losses.
6kW Continuous Power – Delivers full 6kW with ≥97% peak efficiency, lower heat generation than Victor alternatives.
Stable 50V Output for 12S Systems – Perfect for 12S LiPo (50.4V nominal) – direct battery replacement for unlimited tether operation.
