About
The Power Supply System [with battery unit] is engineered to provide power to satellite subsystems. Released in 2018, it has a guaranteed service life of 1 year and an estimated production/delivery time of 2 months. The system utilizes a power supply unit for power control in conjunction with a battery unit for energy storage and can support up to 14 solar panels as an electrical source. Key features include three independent charger units with Maximum Power Point Tracking (MPPT) functionality, input converters with up to 86% efficiency, and support for solar panels with coils. It offers four output channels with current limits, a failsafe output switch with timers, RBF switch connection, a long-period hardware watchdog circuit, and rich telemetry. The system has flight heritage, having been launched on the SiriusSat-1.2 satellites on August 15, 2018. It is not adaptable to customer requirements.
