4.2.4.2 Remote Sense
The power supply has remote sense return (ReturnS) to regulate out ground drops for all output
voltages (+3.3V, +5V, +12V, -12V and +5VSB). The power supply operates within the
specification shown in Table 19 over the full range of voltage drops from the power supply’s
output connector to the remote sense points on the server system boardset.

Output Max Drops Units
+3.3V 250 mV
+5V 250 mV
+12V 500 mV
Remote Sense return 100 mV
4.2.4.3 DC and Transient Load Output Voltage Limit
The power supply will maintain regulation specified in Table 20 under all specified conditions,
including parallel operation with other power supplys, line variations, load variations, transient
load conditions, peak ripple/noise, maximum remote sense drops, subsystem hot swap, and
temperature change. The +3.3V, +5V, and +12V output voltages should be measured at their
respective remote sense points. The output voltages must stay within regulation requirements
with the remote sense regulating out the maximum drops shown in Table 19.
