MCE Power
From MCEWiki
There are different solutions for powering up an MCE.
- Linear Supplies
A straight-forward method is to use linear supplies:
- 3V @ 5A (3.3V OK)
- 4.5V @ 3A (5.0V OK)
- 6.3V @ 15A (7.0V OK)
- -6.3V @ 2A (-7.0V OK)
- 10.0V @ 1A (15.0V OK)
Note: 10V supply only used when Readout Card Rev. B or Bias Card Rev. D is present in a subrack. 10V was used to generate reference voltages for DACs.
- Switching Supplies
- PSU + ACDCU
The MCE can be equipped with a switching supply (PSA) that is powered by +-150V DC generated by an external AC-DC unit that can reside far from the MCE and is also supplied by UBC.
So far, there has only been one incident that the switching noise was reported to be unacceptable.
