1992 Shuttle Small Payloads Symposium
The launcher electronics block diagram is shown in Fig. 6. Two 12-volt batteries provide power, each with six lead-acid cells with 4 amp-hour rating. Power converters include a 12V-28V unit for the indicators on the SPASP and a 12V-5V unit for the logic and relay drivers. ... The logic circuit is a set of static gates that convert switch actions into responses to satisfy operational and safety requirements.
