Calculation Example Of Power Capacity - FATEK M Series User Manual

Chapter 4 Power Wiring, Power Consumption Calculation, and Power Sequence Requirements

4-3 Calculation Example of Power Capacity

Power module selection is depending on the sum of current consumption of all modules. Therefore, user
must know the current consumption of each module. Please refer to the maximum current consumption of
expansion module table, which has the maximum current consumption of each expansion module.
User must consider the match between power and expansion modules cannot cause output power of any one
group of overload use.
Example 1: The below diagram is a System Modules, try to calculate the power supply used of the system.
