The Ecuadorian Space Agency (EXA) COLOSSUS is a Power Conditioning and Distribution Unit (PCDU) designed for space applications.

It integrates EPS, TITAN2 Batteries, and UMPPT Solar Management including release and deploy control with a powerful MCU and 32GB onboard storage in a single unit from a minimum of 400W/hr to 8000 W/hr, from 8 to 56 power rails with power outputs as high as 150W per rail.

From small satellites to large systems like Space Tugs and Launch Vehicles, COLOSSUS enables a high energy density, low volume, and mass solution for a modular, scalable approach to high power requirements missions.

The COLOSSUS PCDU is fully customizable to your mission’s need in terms of power rails, output power, cable, connectors, or interfaces and options are available as an integrated Carbon Nanotubes Thermal Transfer Bus (CN/TTB) shield which allows missions to reuse the spacecraft self-generated heat. It also comes shielded internally to attenuate SUEs and SLEs.

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 the customers have payloads that require huge loads for a short period of time, they 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.
