Assigning Power Supplies
Note the amount of power each module requires and assign it to a power
supply output. Continue to assign modules to the power supply output until
the supply’s output power rating is consumed. The graphic below shows the
number of modules per power supply output.
Each power supply output in the FLEX Ex system is rated for 8.5 W.
Modules can be attached to the output until their combined power equals
that number. Do not exceed the power supply maximum of 8.5 W.
