axl PDB 400A

The axl PDB 400A (Octa) is a professional-grade, high-capacity power distribution board meticulously engineered by axldrone for enterprise-level heavy-lift drone platforms and demanding high-power unmanned systems. Serving as the centralized electrical command center, this compact and highly efficient module safely routes massive power reserves from high-voltage battery packs straight to your aircraft’s electronic speed controllers (ESCs). Designed and manufactured entirely in India, it handles a monumental continuous distributed load of up to 400A. It features a wide input voltage range from 14V to 60V, making it natively compatible with advanced battery setups up to a 14S LiPo configuration. By organizing complex power paths, the axl PDB 400A ensures stable, failure-free operation under punishing industrial flight profiles.

MOSFET Soft-Start and Dual High-Output BECs

Connecting massive high-voltage batteries to large multirotor ESCs typically induces devastating power surges and terminal arc erosion. Therefore, the axl PDB 400A integrates an advanced, MOSFET-based solid-state power switch design. This specialized hardware guarantees a controlled, soft-start power sequence that completely eliminates connection sparks and shields delicate downstream electronic components from inductive loading shocks. Additionally, the board features integrated dual step-down DC-DC regulators (BECs) that deliver fully regulated, ultra-clean 5V and 12V power lines simultaneously. These low-noise auxiliary channels provide dedicated power to flight controllers, high-draw telemetry links, thermal payload gimbals, and auxiliary computer nodes without risk of electrical interference.

Telemetry Precision and Heavy Multi-Rotor Setup

Maintaining complete situational awareness during critical long-range BVLOS operations, infrastructure inspection, or heavy agricultural spraying requires impeccable real-time system diagnostics. The axl PDB 400A incorporates a built-in, high-precision Hall-effect current sensor. This electromagnetic sensor continuously tracks total system power draw, broadcasting highly accurate live telemetry metrics directly to your autopilot system. Tailored for heavy-duty octacopter or X8 coaxial layouts, the board provides 8 distinct 60A ESC output paths. This spacious configuration enables technicians to execute clean, organized high-gauge soldering, preventing messy overlapping wiring clusters and streamlining routine maintenance checks.

Technical Excellence and Airframe Integration

Investing in authentic axldrone hardware safeguards your expensive imaging payload and multirotor infrastructure from catastrophic voltage sags. The foundation of this high-amp PDB is manufactured using premium, high-density FR4 material, which serves as a superior electrical and thermal insulator. Measuring a compact 10.6 cm by 8.7 cm with a lightweight footprint of just 55g, it can be seamlessly integrated into tight internal electronics bays without disturbing your multirotor’s native center of gravity. It stands as an indispensable asset for commercial fleet operators, academic research labs, and defense integrators demanding unyielding electrical reliability and type-certification readiness in extreme environmental conditions.
