COLOSSUS L1C: All-in-one PCDU
The COLOSSUS L1C PCDU is a Cubesat/Small Satellite format Power Conditioning and Distribution Unit designed to provide the highest energy capacity and redundancy. It integrates EPS, TITAN2 Batteries and UMPPT Solar Management including release and deploy control with a powerful MCU and 16 GB onboard storage in a single unit delivering up to 400W of regulated power.
COLOSSUS includes the PowerFlex® technology, which allows the user to generate up to double the nominal power of the PCDU in case of peak demand: This means that if you have payloads that require huge loads for a short period of time, you don’t need to dimension the whole PCDU for it, COLOSSUS can rush up to 2 times the power surge needed and serve those needs safely and under some conditions, up to 4 times.
