To calculate the IPC's current requirements and power consumption, select all installed
components from this table and list them e.g. as shown below (a power supply with a 24 VDC
supply voltage is required):
With this structure, you have four current values (one for each voltage supply), which are
multiplied with the associated voltages to determine the power consumption (P = U * I).
You then add the power ratings for the respective supply voltages, which results in the total
power consumption for the IPC.
Please note, that maximum values for current requirements and power consumption, listed in the
"Current Requirements of the Components" table must not be exceeded!
