The ISIS Modular Electrical Power Subsystem version 2 (v2) is the second-generation modular EPS designed and manufactured by ISIS. IMEPSv2 is designed as a flexible EPS targeting larger nano-satellites and microsatellites from 3U upwards. Using recent high-performance technology, the EPS provides improved efficiency over the previous version while minimizing EMI. The modular architecture allows the EPS to be tailored to the needs of the platform without needing customization. The distributed design philosophy that underpins the IMEPS design allows unprecedented flexibility in output bus count and voltage, and enables tailorable redundancy to be applied for selectable parts of the platform, depending on the needs of the mission.
The IMEPS consists of four types of elements:
One or more of each of these units can be combined to form the platform EPS.
Additional – Battery packs
Additional – Conditioning Units
