Power Supply Capacities
The Power Supply on the CPU or NIU module provides +5V and +3.3V power to the
modules in the station. Booster Power Supplies can be used if the modules in the system
will draw more current than the CPU or NIU Power Supply can provide. The AC or DC
Power Supply on the CPU or NIU and the Power Supply that resides on the Booster
Carrier must share the same external power source.
For each Power Supply, the maximum total combined output current from the 5V and
3.3V outputs is 1.5 Amps. Each power supply provides a maximum of either 0.25 Amp or
1 Amp on its 3.3V output, as listed in the next table. That portion of the Power Supply’s
total output current not drawn from the 3.3V output is available via the 5.5V output.

Power Calculation Example
In the example system listed below, the maximum current draw on the Power Supply’s
3.3V output by all of the modules will be 0.215 Amp.
Subtracting 0.215A from the Power Supply total output of 1.5A shows that 1.285A will be
available via the 5.5V output:
(1.5A – 0.215A = 1.285A)
Because the maximum current draw on the 5V output would be 0.65A as shown in the
table below, any of the available Power Supplies could be used for this system.
