212 DC Common Bus Applications
Common Bus Capacitance
Example In the example below, the sum of the leader IAM power rail modules
capacitance and the follower IAM power rail modules capacitance (1984 µF
and 1340 µF) equals 3324 µF total bus capacitance. This configuration does
not exceed the maximum total bus capacitance of 3420 µF for a common bus
Kinetix 2000 system.
