NanoAvionics Electrical Power System EPS

The NanoAvionics EPS Maximum Power Point Tracking (MPPT) power conditioning and distribution unit, designed to meet wide variety of customer requirements, with high, up to 96 %, MPPT and output converter efficiency. The EPS is compatible with different size and configuration of solar panels without any additional hardware or software configurations as it is equipped with four MPPT converters with eight solar panel input channels, with wide range input voltage (2.6 – 18 V) for reliable and flexible power distribution. Each MPPT converter is integrated with Maximum Power Point Tracking capability for high, constant and efficient energy harvest.

Four output converters, two of which can be voltage configured (3 – 18 V), with ten configurable output channels, allow a high number of subsystems to be connected to the EPS and ensure reliable power distribution due to integrated, hardware and software configurable overcurrent protection features.

NanoAvionics EPS comes with ready to use on-board Lithium-Ion batteries with integrated Battery Management System (BMS) which help to prolong mission lifetime and ensure appropriate operating conditions. The EPS can also be configured up to 161 Wh battery capacity, for power hungry systems due to external battery pack support. By using external battery pack EPS can provide up to 175 W of output power.

On-board monitoring and logging features allow the user to easily monitor the EPS operations in all input and output circuits. In the event of an unexpected malfunction occurrence, the EPS watchdog system ensures that the satellite and EPS are rebooted and brought back to reliable, working condition.

Additional support hardware, such us an external battery charger, that come with the EPS allows the user to quickly and effortlessly set up the system for immediate work. The implemented USB port supports EPS configurations for user friendly operations. Industry approved, decentralized communication interface (CAN) with CSP protocol allows plug-and-play EPS integration to the main network
