Agras T50 Power Distribution Board Module PN 301-00000-14 | High Voltage Management

In the design of heavy-lift remotely piloted aircraft (RPAS), power management is the cornerstone that supports both propulsion and mission systems. The Power Distribution Board (PDB) module of the Agras T50, Part Number 301-00000-14 , is the electrical nerve center of the aircraft. In aerospace operations, failure of a distribution bus can lead to the total loss of the platform; therefore, this component is designed under stringent standards of current surge tolerance and thermal dissipation.

For the Agras T50, which operates with extremely high currents to support its high-traction motors and centrifugal spray systems, the PDB acts as the critical mediator between the intelligent battery and all ESCs (Electronic Speed ​​Controllers). At Magallan Aerospace Supply , we treat this unique module as a flight safety item, essential to ensure that power delivery is linear, safe, and protected against electromagnetic interference.

What it is and how it works.

The PN 301-00000-14 Power Distribution Board is a high-conductivity, multi-layer unit that acts as the drone's central power hub. Its primary function is to receive the raw voltage from the battery and distribute it in a branched fashion to the aircraft's arms, radar sensors, flight controller, and payload systems.

The operation is based on thickened copper busbars that minimize internal resistance and voltage drop . In addition to power distribution, the module integrates filtering circuits that protect sensitive components against electrical noise generated by the rapid switching of brushless motors. It also acts as a communication interface, allowing current consumption telemetry data to be sent in real time to the aircraft's Central Processing Unit.

Operational Applications in Aviation and Drones

Power Bus Centralization

It acts as the convergence point for all high-current harnesses, eliminating wiring complexity and reducing points of failure due to loose connections or excessive resistance.

Mission Systems Protection

It distributes regulated low-voltage power to critical sensors, such as the Front Scanning Radar and the Binocular Vision System, ensuring that they remain active even under maximum demand from the traction motors.

Structural Maintenance and Repair (MRO)

A fundamental component in the reconstruction of aircraft that have suffered electrical damage due to overload, infiltration of corrosive liquids, or impacts that compromised the integrity of the original busbars.

Technical and Operational Benefits

Operational Reliability: Circuits designed to operate under high temperature conditions without degradation of conductivity.

Precision in Current Delivery: Ensures that each ESC receives exactly the same voltage, allowing for balanced thrust and stable flight.

Reduced Thermal Failures: Optimized layout for heat dissipation, avoiding hot spots that can lead to connector meltdown.

Simplified Integration: Quick-connect ports and reinforced solder points that follow the OEM standard for a drop-in replacement .

Performance Optimization: The low impedance of the plate improves the efficiency of the propulsion system, resulting in marginal, yet critical, gains in flight range.

Key Technical Differentiators

Reinforced Layered Construction: Industrial-grade PCB with multiple layers of high-grammage copper to withstand current surges during evasive maneuvers.

Conformal Coating: Protective layer against moisture and chemical corrosion (fertilizers and pesticides), essential for longevity in harsh agricultural environments.

High Amperage Connectors: Terminals designed to support the T50 system battery connections without generating an electric arc or contact resistance.

Signal Isolation: Physical separation between high-power traces and data traces, preventing corruption of command signals (EMI).

Compatibility and Installation Requirements

Target Aircraft: Exclusive to Agras T50.

Installation Requirements: Requires partial disassembly of the central fairing and cooling module. The use of antistatic tools is recommended, as well as rigorous verification of all power connection screw torques.

Synchronization: After installation, it is recommended to check the voltage telemetry via the control application to ensure that all distribution channels are operating within nominal parameters.

Important Technical Guidelines and Considerations

1. Connector Inspection: Before closing the aircraft, check for any metallic debris or solder residue on the board, which could cause a catastrophic short circuit.

2. Protective Handling: Because this is an electronic component sensitive to ESD (Static Electricity), it should only be handled by its edges and with a grounding wrist strap.

3. Leakage Check: Ensure that the seal of the drone's central compartment is restored after the board replacement to maintain the aircraft's nominal IP protection.
