The PowerBox Champion SRS is a high-end power management system designed for demanding RC pilots, featuring 24 servo outputs with individual ServoMatch and a door sequencer with an integrated setup assistant. It incorporates four high-performance voltage regulators that can be independently set to 5.9V or 7.4V, supporting both HV and conventional 6V servos. The unit supports serial receiver systems from Spektrum, Futaba, JR, Multiplex, HoTT, and Jeti, with telemetry output for battery, receiver, and GPS data. A graphic LCD screen and SensorSwitch enable intuitive menu-based programming, while the flight recorder logs lost frames, fail-safe events, and battery data.
