Power Supply Selection
To determine which power supply to use, calculate power requirements below.
ATTENTION
Using inadequate power supply will cause the controller to cycle power on and off.
Enter quantity of each module type in column A and calculate the 5V and 24V maximum current in
columns D and E. Sum the maximum current for all module types and determine if the 900P02 power
supply is appropriate.

1.
Is total 5V less than 2000?
Yes/No
2.
Is total 24V less than 900?
Yes/No
3.
If the answer to 1 and 2 are YES, go to 4. If the answer to 1 or 2 is NO, use power supply 900P01-0001.
