For general MCE power requirements, see MCE Power Requirements.
The power consumption during normal operation is listed here. The actual cosumption may vary depending on MCE firmware parameter settings, etc. The numbers below are 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 |
