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.

Readout Card | B | 25.5 |
Bias Card | F1 | 2.1 |
Bias Card | F0 | 4.8 |

+Vcore | 1.11 A | 0.85 A |
+Vlvd | 0.20 A | 0.20 A |
+Va | 1.11 A | 3 to 3.3 A |
-Va | 0.37 A | 0.25 A |
+Vah | unused | 0.005 A |
Bias Card
supply | Rev. F11 | Rev. F0 | 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.

+Vlvd | 1.60 A |
+Va | unused |
