Overview
Crystalspace P1U power supply is the smallest and most advanced power supply in the market. It suits well for densely packed 1 and 2 unit CubeSats. It uses fast maximum power point tracking boost converters to charge an integrated doubled battery pack. Battery output is fed through duplicated converters that can provide 3.3 V, 5 V, 12 V. Unregulated 3.7 V battery and regulated buses are
available through individually selectable current limited and latch-up protected switches. Pinouts, output voltages, and channels are changeable to user needs. Each sold unit has gone through acceptance testing.
