About
The Deployment Sequencer BU-36 is a crucial component for satellite deployment. Upon receiving an activation signal from the Launch Vehicle (LV), it initiates the mission cyclogram, providing targeted output signals to trigger the deployment of each satellite. Simultaneously, it transmits telemetry information back to the LV, confirming both the actuation of mechanisms and the successful deployment of satellites. This ensures reliable and controlled separation of payloads in orbit. The device features 36 control channels, operates within a temperature range of -35°C to +60°C, and has a mass of 5.5 kg. It provides a payload supply voltage of 28 V, with a current of 2 A per channel and a maximum total current of 4 A, powered by a 4 Ah battery.
