3.4.2 5 V Rail Overload Check
The PS-12 and PS-22 modules supply 5 V
DC
to the backplane for powering modules. A
maximum of 3 A (5 A for PS-x2 v1.5 or above) can be drawn on the 5 V
DC
rail from each
power supply module.
Please ensure that this limit is not exceeded by totalling the 5 V current requirements for
your RTU.
