Each MXL System enclosure requires a
power supply. This can be either an
MMB-2, PSR-1, PS-5A or PS-5N7. To
ensure that the power supply is not
overloaded, complete the worksheet
on the following page.
 Enter the quantity of each module
in the enclosure.
 Calculate both the 24V and 5V
loads for each row.
 Total the Active 24V and Active 5V
columns.
 Ensure that both totals are within
the power supply output ratings in
the table to the right.
