Before second 0 already
2.9 kJ (2892 Ws) were taken for 28 seconds.
After second 30
output is disconnected.
From second 0 3.34 kJ (3336 Ws) were taken for
further 30 seconds.
Example 2
E = 24 W · 2 sec + 0 W · 2 sec + 120 W · 8 sec + 108 W · 2 sec + 120 W · 2 sec + 96 W · 4 sec + 120 W · 11 sec + 108 W · 5 sec + 120 W · 6 sec + 48 W · 2 sec +
108 W · 8 sec + 0 W · 1 sec + 96 W 3 sec + 84 sec · 2 sec= 5844 Ws ≈ 5.84 kJ
UPS output is disconnected after 58 seconds because the output energy exceeds 5.57 kJ.
.
Example 3
E = 72 W · 2 sec + 120 W · 6 sec + 96 W · 2 sec + 108 W · 6 sec + 84 W · 3 sec + 120 W · 5 sec + 84 W · 6 sec + 96 W · 3 sec + 120 W · 20 sec +
96 W · 5 sec = 6228 Ws ≈ 6.23 kJ
UPS output is already disconnected after 30 seconds because the output energy (of the last 58 seconds) exceeds 5.57 kJ.
