The power consumption during normal operation is listed here. The actual cosumption may vary depending on MCE firmware parameter settings, etc. This is calculated based on Vcore = 3V, Vlvd=4.5V, Va+=6.2V, Va− = −6.2V, Vah=10V.

Card Revision Power (W)
Clock Card B 8.73
Readout Card E 13.4
Readout Card B 25.5
Bias Card F1 2.1
Bias Card F0 4.8
Bias Card D 2.1
Address Card D 8.4

A simple form, based on the tables given below, to compute the power requirements of a subrack populated with user-selectable cards is available: http://e-mode.phas.ubc.ca/mce/cgi-bin/power.cgi

Clock Card

Supply Rev. B
Vcore 0.3 A
Vlvd 0.5 A
Va+ 0.9 A
Va− unused
Vah unused

Readout Card

Supply Rev. E Rev. B
Vcore 1.11 A 0.85 A
Vlvd 0.20 A 0.20 A
Va+ 1.11 A 3.0–3.3 A
Va− 0.37 A 0.25 A
Vah unused 0.005 A

Bias Card

Supply Rev. F11 Rev. F00 Rev. D
Vcore 0.09 A 0.09 A 0.05 A
Vlvd 0.12 A 0.12 A 0.07 A
Va+ 0.12 A 0.36 A 0.12 A
Va− 0.08 A 0.28 A 0.12 A
Vah unused unused 0.02 A

1 In Rev. F1, in order to save power, L12 and L13 (ECO-055) are removed to disable regulators U34 and U35 supplying +/-5V to the low noise bias channels. This results in total of ~2.7W power saving.

Address Card

Supply Rev. D
Vcore 0.40 A
Vlvd 1.60 A
Va+ unused
Va− unused
Vah unused
