3.
Connect one end of the shield of the twisted pair wire to the chassis ground point
on the power supply.
4.
Connect the positive sense line (+SNS) from the positive regulation point as close
as possible to the load terminals to pin J1-1.
5.
Connect the negative sense line (-SNS) from the return of the load to pin J1-6.
To compensate for losses in power leads connected to the output, the power supply
provides sense connections beside the output terminals. With remote sense leads in
place, the power supply regulates to the displayed voltage at the point where the sense
lines are connected to the output leads. With the sense lines disconnected, the power
supply regulates the voltage at the output terminals.
CAUTION: Equipment damage
Do not operate the power supply with sense lines connected to the load without
also connecting the load power leads to the output terminals.
CAUTION: Reverse polarity
Avoid reversing positive (+) and negative (-) sense connections. When using
remote sense to compensate for load line losses, ensure that the positive sense
line is connected to the positive load terminal and the negative sense line is
connected to the negative load terminal. Do not reverse these connections or the
power supply may be damaged.
Important:
Long load leads with large capacitance at the load and remote
sensing can cause voltage instability due to inductance of the load leads.
Measures to reduce inductance and/or capacitance (raising resonant frequency)
or using local sense can be beneficial in stabilizing the system.
