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.
