Selecting the Right Power Supply Unit

The AMAX-5580 needs an external 24VDC power input from the screw terminal on
the top. And this power input will supply power to the main CPU module (AMAX-
5580) and left-hand-side PCIe expansion modules (AMAX-54XX).The pin definition is
as below:

4 V2+
5 V2-
6 RL+
7 RL-
To keep the system working properly, the user has to calculate the system power
consumption to select the proper power supply unit. The selected power supply
should provide more power than the max power consumption of the system.
For example:
Item Model
1 AMAX-5580
2 AMAX-5424V
3 AMAX-5490
We suggest adding a tolerance on the total power consumption and also consider the
power de-rating effect in your application environment. Below is a suggestion list of
verified power supply units:
