TMN/TMP MODULE CONNECTIONS
If the TMN/TMP module or modules are used separately from the rack or in a
user configured rack, connections should be made to the high-reliability hotswap
connector on the back of the module with the functions as shown in Figure 9.

DESCRIPTION

+ Sense
- Sense
This is an analog control signal made up of the current share
signals of all modules connected together. This pin is used to
connect to Pin 10 of another identical rack to share output
currents. Output currents between racks are shared within an
accuracy of 10% of full load current over a 50% to 100% load
range. This signal is referenced to -Sense, Pin 23.
These remote sense leads should be connected as a twisted pair
to the resp and - load points to provide regulation at the
point of load. Removal of the sense leads transfers regulation
control to the output terminals of the rack via internal 10-ohm
sense resistors.
