the voltage drop due to load lead resistance and/or blocking diodes if used. The maximum voltage drop between the
load and sense connections should not exceed the maximum voltage specified for that module.
Always observe the following general rules for remote sense operation: -
a. Ensure that the remote sense cables are twisted pairs.
b. PCB tracks for remote sense should be run back to back.
c. Ensure that the remote sense cables / tracks are as short as
possible.
d. Ensure that the sense cables are not twisted together with the
power cables.
e. PCB power tracks and remote sense tracks should be kept away
from each other as far as is possible.
f. Do not fit components (resistor, inductor or diode) into remote
sense lines. This could make the system unstable.
g. See the data sheets for each module to see the maximum
voltage drop that remote sense can compensate for, do not exceed
this value.
