SUPERNOVA POWER SYSTEM

Overview

The Supernova Power Conditioning and Distribution Unit is a 28V, 300-1500W solar array, battery and load management system for small satellites, high delta-V vehicles, and missions to cislunar or deep-space destinations. Due to its modular design, it can be scaled to exactly to the needs of the mission – achieving the power levels, output configuration and redundancy philosophy that you need. As part of the Bradford Avionics Stack, it features high performance for its size and mass, critical single-point failure tolerance throughout, and can achieve considerable integration cost and risk savings. Supernova can be supplied as part of a larger integrated avionics solution, or as a stand-alone subsystem.
