Calculate 24V DC Control Power Current Demand
If using the 24V DC shared-bus connection system to distribute control input
power to a drive cluster, output current from the 24V power supply must not
exceed 52 A.

(1) These values represent only the iTRAK power supply. They do not include the iTRAK motor modules that are connected to the iTRAK power supply and also draw current
from this 24V control power input. For more information regarding 24V control power requirements, see the iTRAK System User Manual, publication
(2) Values are base current per module.
(3) Values assume two brake motors, each drawing the maximum rating of 2 A, are attached to each module.
(4) Values assume the maximum rated brake current of 5 A.
(5) Inrush current duration is less than 30 ms.
IMPORTANT
If the 24V control-power output current (based on your system
calculation) exceeds 52 A, you must add another 24V power supply. To do
this, you can insert another 2198-TCON-24VDCIN36 control power input
wiring connector at any point in your drive cluster.
