PBmain High-Integration Power Management Board (PDB)

Engineered for Small-to-Medium Uncrewed Systems

The PBmain is a premium, highly integrated Power Management Board purpose-built for small-to-medium uncrewed systems requiring extreme power density and bulletproof reliability. Supporting up to a 12S LiPo battery setup and handling a maximum current of 250A, the PBmain serves as the ultimate power backbone for high-performance industrial platforms.

The board features four high-current, 50V outputs utilizing rugged XT90 connectors, alongside integrated 24V, 12V, 7.5V, and 5V step-down regulators—with comprehensive overvoltage protection (OVP) safeguarding every single rail. For mission-critical reliability, the servo/actuator power supply utilizes a dual-channel redundant architecture and supports full bidirectional communication with the flight controller (FC).

Equipped with dual independent navigation light controllers, an onboard Hall-effect current sensor (up to 200A), and a wide-range temperature sensor (-55°C to 125°C), the PBmain provides complete system telemetry. Multi-channel voltage monitoring and an integrated buzzer ensure the system triggers instant acoustic alerts the moment an anomaly is detected.
