Key highlights
The Space Resources Lab EPS Board is a compact, high-efficiency power system designed for CubeSats. It features four independent MPPT-enabled solar charger channels using the LT3652, each optimised for maximum energy harvesting in space conditions. The power distribution board includes Schottky diodes, resettable fuses, and TVS protection, while NTC thermistors monitor thermal health across all battery lines. Designed to support lithium-ion battery packs, the board ensures safe, intelligent charging and robust power delivery to payloads and subsystems.
Standardised to the PC/104 footprint, this EPS is fully compatible with Space Resources Lab’s CubeSat structures, battery packs and solar arrays.
