The solar panels utilize Hirose 1.25 connectors for both power and digital interfaces, with a 4-pin connector for power output and an 8-pin connector for the temperature and light sensor. This configuration is used up to a 3U panel. A 6U configuration with two strings provides two sets of 4-pin connectors for power output.
The panels have passed thermal cycle, thermal vacuum, outgassing, and random vibration tests. Each unit is tested prior to shipment and packed in a clean container under ISO Class 5 environments. Contact Aphelion for alternate configurations and interfaces, as well as to inquire for compatibility with other products.
The PBM is an integrated EPS and OBC solution designed for mission-critical, volume constrained environments. Features such as maximum power point tracking, individually switchable and monitored output rails, high discharge battery compatibility, and a high-performance Cortex M4 processor allow the PBM to be adaptable for multiple mission scenarios.
*Tested at 135.3W/m2 irradiance and at 25°C.
