MVD Low Voltage Power Supply Specifications 12-2-97

These specifications are for power supplies for MVD front-end electronics including MCMs, Daughterboards, Power Communication Boards and Motherboards as well as various Interface modules on racks.

[Note added 18 May 99: only types A,C and E are used in the end. See hvlist.html for an updated list]


A. Summary of supplies

Supply Type Qty Nominal Output Voltage > Maximum Current per each Usage
Type A 4 +6.8V 30 analog, for four groups of MCMs, Daughter and Power-Communication boards (each group per each Motherboard)  
Type B* 4 -6.8V 6 analog, for four groups of MCMs, Daughter and Power-Communication boards (each group per each Motherboard)  
Type C**   4 +5.3V 25 digital, for four groups of MCMs, Daughter and Power-Communication boards (each group per each Motherboard)  
Type D 4 +5.3V 50 digital, for two groups of Glinks + Interface modules + Motherboard  
Type E 2 +12/-12V 5 analog, for interface modules + Motherboard  
 * This supply may be substituted by Type-A if development cost of another type is not justified.
**This supply may be substituted by Type-D if development cost of another type is not justified.
