CMS LV Power System
Proposed System Design -1• Hard Wired Sensors – Continuous monitor (Temperature…)• If Detector ‘Safe’ switch on Control System(Low Power Dissipation)
• Control System (Tracker and ECAL use Tracker System)
• DCU provides comprehensive sensing of Detectors• If Detector ‘Safe’ prepare to switch on Low Voltage System• ‘Set-Up’ LV Regulators on Front End Electronics (ECAL)
• Sequentially bring on Low Voltage Power Systems
