VECTRONIC Aerospace offers with the VPCDU a highly integrated device to control the power supply of the subsystems of a small satellite. The VPCDU incorporates interfaces to solar arrays and batteries, power outlets to the satellites subsystems, functionalities for separation detection micro switches, under voltage lookout, battery handling and power conditioning. The power outlets to the satellite’s subsystems are equipped with resettable electronic fuses to prevent the system from damage in case of an overload or malfunction of external devices. Most of the internal functions are controlled by a micro processor unit in redundant configuration.
