Electrical Power Supply system for small nanosatellites
The NanoPower P31u power supply are designed for small, low-cost satellites with power demands from 1-30 W. Employing a strictly KISS design philosophy, the P31 interfaces to triple junction photo-voltaic cells and uses a highly efficient boost-converter to condition their output power in order to charge the provided lithium-ion battery.
