2.4 Power Supply
Introduction
The A
X
M node contains a power supply (55 amp) that is used in many
other LCN node types.
It is capable of producing output voltage margins of +5% and -5% that, in
some cases, are used in factory test and troubleshooting activities. This
margining is controlled by the jumper on the face of the power supply. See
the following diagram.
Similar power supplies are used in both the K2LCN (Five-slot) and HMPU
(Ten-slot) versions of A
X
M.

The low power margin (-5%) must never be used in the A
X
M.
The coprocessor and hard disk drive design allows for only a
-2.5% margin. Using -5% margins will produce unpredictable
results.
The high (+5%) power margin can be used by factory test
and during troubleshooting activities. Honeywell does not
recommend using any power margins while a node is on
process.
