Calculation of 5V DC power supply capacity (current consumption)

Confirm the current consumption using the following procedures.
When the main unit built-in power supply is insufficient, add an extension power supply unit (FX
in accordance with the necessity.
1) Calculating the current in extension equipment that can receive power from the main unit built-in power
supply.
Check whether the current consumption of extension equipment to be connected is not more than the
capacity of the main unit built-in power supply.
