  • Magnet Instrumentation and Power Supplies
    This provides an overview of the system. Specifics for the power supplies can be found among the links below.
  • FuG Power Supply Schematics
    Schematics and physical outline of the FUG power supplies with notations in english. The english translation is not the best, so be prepared to have to do some interpreting of your own. I traced out the Left Q3 schematics for each of the control modules. Heidi and I made corrections to the schematics and verified the wiring on the "backplane" connectors. Notations were added to the schematics to try to make the schematics more useful. The Fast Electronics Group looked at some of the modules from the other three FuG power supplies and found them to be "electrically identical". That is, any visual differences are strictly cosmetic. Jumper wires serve the same function but are run to different points on the board, for example. I did a cursory examination of the boards and found this to be true, also. So, we are using the LQ3 schematics as the reference schematics. Differences we are aware of can be found in the directories specific to LQ2, RQ3, and RQ2.
  • FuG NTN Series Power Supply Operating Instructions
    This is an english version of the operating instructions. The english translation is not the best, so be prepared to have to do some interpreting of your own.
  • FuG Power Supply Panel Layouts
    The drawings of the exterior appearance of the power supplies. I'm not sure what the last page is supposed to be. It does not seem to be something that is installed on the supplies; it appears to be the space underneath the transistor banks and I assume it was the original water supply connections for cooling the supply. The 480VAC main lines are connected to the terminals in the bottom right of the drawing.
  • EPCT Instruction Manual
    The EPCT module, manufactured by Eukontrol, is a variant of the zero flux current transducer.
  • EPCT Schematic
    This is the EPCT circuit as I was able to trace it out. It is not a schematic provided by the manufacturer.
  • Data Sheet for Manganin Wire
    The FuG schematics claim this is the wire used to make the resistors on the transistor banks.
  • Data Sheet for the Polarity Reversal Switch
    The power supply is a dual quadrant supply, it only puts out one polarity of voltage and sinks and sources current. To get the opposite voltage polarity, and current flow, one needs to swap the connections to the load.
  • Mass Flow Meter Readout
    These are the meters that monitor the cold gas flow over the leads that make the warm to cold temperature transistion
  • Short Breakout Rack
    This rack has the cable breakouts mounted internally, the isolation modules for a couple of the signals, and the mass flow meters.
