3. Connect one end of the shielded 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 J1.1.
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.
