PDB-120V Wide Voltage Power Distribution Board | Designed for UAVs

As industrial drones continue to expand into more sophisticated and high-demand applications, extended flight endurance, increased payload capacity, and enhanced system stability have become critical drivers of technological advancement. At the core of these capabilities lies a robust and reliable “power heart.” We are proud to introduce the PDB-120V high-voltage power management module, specifically engineered for high-voltage drone platforms. More than a conventional power distribution solution, it combines intelligent power management with high-efficiency thermal control, establishing itself as a future-ready central power hub for advanced UAV operations.

The PDB-120V features wide-range 36–120V high-voltage input support, allowing seamless integration with large-capacity HV battery packs and maximizing power potential. Unlike many modular, single-function power units on the market,the PDB-120V is designed for high integration and intelligent power management, delivering a comprehensive and reliable solution for advanced UAV platforms.

Redundant Design, Safety Monitoring & Multiple Regulated Outputs

The PDB-120V provides dual power supplies for the flight controller

POWER 1 (Primary Supply): Connected via the GH12P interface to the main power input of flight controller. It also supports real-time voltage feedback, allowing the flight controller to monitor power status accurately.

POWER 2 (Backup Supply): Provides 5V XT30 output for the POWER 2 of flight controller, enabling redundant backup or extended power support.

In addition, the PDB-120V offers 5V/12V/24V regulated outputs, simplifying wiring and enhancing overall system reliability.

Real-Time Voltage Monitoring for Enhanced Situational Awareness

The GH12P connector not only powers the FC but also returns the main battery voltage directly to the flight controller—no external voltage sensor required.

Battery status can be displayed in real time in Ground Control Station (GCS), providing pilots with early low-voltage warnings and supporting comprehensive battery health assessment.

Three Independent Regulators for Flexible Power Supply

Provides three independent outputs: 5V / 12V / 24V, all equipped with reliable XT30 connectors. Each output channel can deliver up to 2A of clean, stable current, ensuring consistent performance under load.

With substantial power capacity (e.g., 24V continuous 48W, peak 120W), the module can easily support high-demand onboard equipment, including heavy-duty gimbals、searchlights、loudspeakers.

Active Cooling — Optimized for High-Temperature Operations

The PDB-120V features an active cooling fan combined with a multi-layer PCB thermal design, effectively minimizing temperature rise under heavy load conditions.

This design prevents thermal throttling or unexpected shutdowns, ensuring reliable and stable performance during high-power operations or extreme-temperature environments.

Product Parameters

Typical Application Scenarios

The PDB-120V is engineered to be the premier power hub for advanced, high-performance UAV platforms.

Long-Endurance Industrial Drones

Operational Requirements: The platform must support multi-sensor payloads, including HD video links, LiDAR, and thermal cameras, with continuous operation of 1–2 hours.

Compatibility: 24V/12V high-power outputs, capable of driving heavy payloads directly, eliminating the need for additional DC-DC converters. Its intelligent flight-controller-first power management ensures the FC receives priority power, safeguarding mission reliability and operational safety.

Heavy Lift / Emergency Delivery Drones

Operational Requirements: High-voltage battery packs provide enhanced energy density and deliver stable power to servos, release mechanisms, and communication modules.

Compatibility: Supports high-voltage inputs up to 120V, making it ideal for HV propulsion systems, while the 5V and 12V outputs can be connected directly to actuators and control units for streamlined power distribution.

High-Altitude / High-Temperature Operation

Operational Requirements: Optimized for sustained high-load operation in low-thermal-dissipation or high-altitude environments.

Compatibility: Active cooling combined with a multi-layer PCB design effectively manages thermal buildup, preventing performance derating or shutdowns common with traditional passive cooling modules.

Security UAVs

Operational Requirements: Platforms operating in critical missions require redundant power supply, real-time system monitoring, and built-in fault tolerance to ensure uninterrupted performance.

Compatibility: integrated battery voltage monitoring and over-temperature protection, while the GH12P interface provides direct voltage feedback to the flight controller. This design enhances mission reliability, situational awareness, and operational safety even under demanding conditions.

VTOL (Vertical Takeoff & Landing) Fixed-Wing UAVs

Operational Requirements: Hybrid propulsion architectures in VTOL platforms often experience significant voltage fluctuations, requiring a stable low-voltage supply to support the flight controller and switching logic.

Compatibility: Wide-voltage input accommodates varying battery discharge curves, while the three isolated regulated outputs ensure that the flight controller, video transmission system, and control surfaces operate independently without interference, providing reliable and stable performance in complex flight scenarios.

For UAVs built on high-voltage platforms with multi-payload configurations and medium to large-scale structures, the PDB-120V represents the optimal power management solution.
