Stability
Using remote sensing under certain combinations of load
lead lengths and large load capacitances may cause your
application to form a filter, which becomes part of the
voltage feedback loop. The extra phase shift created by this
filter can degrade the power supply’s stability, resulting in
poor transient response or loop instability.
In severe cases, it may cause oscillations. To minimize this
possibility, keep the load leads as short as possible and twist
them together. As the sense leads are part of the power
supply’s programming feedback loop, accidental
open- connections of sense or load leads during remote
sensing operation have various unwanted effects. Provide
secure and permanent connections.
CV regulation
The voltage load regulation specification in Chapter 7
applies at the output terminals of the power supply. When
remote sensing, add 5 mV to this specification for each 1 V
drop between the positive sensing point and (+) output
terminal due to the change in load current. Because the
sense leads are part of the power supply’s feedback path,
keep the resistance of the sense leads at or below 0.5 Ω per
lead to maintain the above specified performance.
During remote sensing setup, it is strongly recommended to power off (by
pressing the power ON/OFF button) the power supply to avoid undesirable
damage to the load or the power supply.
