If the PSU is powering more than one Controller, the TAMPER and
PSU MON connections need only be connected to one Controller.
The maximum current you can draw from the PSU is 5A at 12V. If the
24V module is fitted in the PSU then the maximum current you can
draw simultaneously from both supplies is 1A at 12V and 1.5A at
24V. For each 0.5A reduction in the 24V supply, you can draw
another 1A from the 12V supply. Make sure these figures are not
exceeded.
