V
● Current change rate:
2 A/µs, T = 1 ms
(CCDHT1 = 0.5 ms;
CCDHT2 = 0.5 ms);
load: 65%–100%–
65%. The bus voltage
is not lower than 11
V, and the time when
the bus voltage is
lower than 11.4 V
does not exceed 100
μs
● Add the 3000 μF
capacitor in the 2+2
backup application
scenario (including
the 2+0 backup
application scenario).
The power is 3900 W
in 100% load
scenarios.
