Description

The Power Conditioning Unit (PCU) is a power management equipment intended for GEO telecommunication applications. It controls the spacecraft power from the solar array in sunlight mode and from 1 or 2 batteries during eclipse.

The PCU generates a fully regulated 50V bus for serving small to medium sized satellites with a power requirement ranging from 2kW to over 6kW, compatible with Electric Propulsion and Time Division Multiple Access (TDMA) payload operation mode. It is based on a modular design and can easily be adapted to different power requirements.

Three Domain Control ensures fully autonomous operation in any operational mode and smooth transition between them. The PCU delivers excellent efficient performance in both transfer and orbit mission configurations.

Highly reliable for mission durations up to 15 years, the PCDU has been designed according to ESA ECSS standards. It is a one failure tolerant unit and after a bus under-voltage event, it is able to restart automatically as soon as any power source becomes available.
