Current and Power Capabilities of MX-2100 Power Supply Modules
The following table lists the power that can be provided by the individual
MX-2100 power supply modules when cooled by free air connection.

Power supply modules of the MX-2100 have load-sharing capabilities. By
installing two KPS modules it is possible to double the allowed loading.
If the power requirements exceed the capabilities of a single power supply
module, you cannot consider that the two modules are providing redundancy.
Any failure must be immediately corrected.
KPS.4
The nominal output power specified for the KPS.4 module can be safely
exceeded to the following maximum output power:
+5V 40W
+12V 18W
–12V 12W
The total power supplied by the module CANNOT exceed the Maximum Total
Power Per Supply of 50W.
KPS.6, KPS.7
The +5V output must always be loaded.
The minimum current consumption from the +5V output is 3A (15W). If a lower
current is needed, use a power supply module with lower output currents.
With forced air cooling, the Maximum Total Power of the module can reach up
to 80W.
