3.3 V Digital 5.0 V Digital MC POWER SUPPLY 14 ESR / MUON DT MINICRATE SYSTEM. Overview. November 3rd , 2003 MC POWER SUPPLY AVERAGE MINICRATE POWER CONSUMPTION: 135 Watts 3.3 V Digital The voltage at chamber input is nominally 4 V (as it is followed by low drop regulators). The current at the load can be any value between 0 and 35 A. PS must be designed to provide at least 20% more current than maximum nominally required: 42 A. The voltage at the Load is nominally 6 V, as it is followed by one low drop regulator. The current at the Load will be any value between 0 and 1.5 A. PS must be designed to provide at least 20% more current than maximum nominally required: 1.8 A 5.0 V Digital
