Remote (Sense) Connection
Background
The electronic load modules have two voltage
sense contacts: Vsense L(black), Vsense R(red).
Voltage sense can be used to help compensate for
long cable length. The longer the cable, the higher
the potential resistance and inductance, therefore a
short cable is best. Twisting the cable can help
reduce induced inductance and using the Vsense
terminals compensates the voltage drop seen
across the load leads, especially leads with higher
resistance. This is useful when used in CV or CR
mode.
WARNING
VsenseR (red) must have a higher (+) potential than
VsenseL (black).
Connection
The diagram below shows how a DUT can be
connected using voltage sense. Note that the sense
wires are also twisted pairs.
Note
The wire gauge for the sense wires should be no
smaller than 16 gauge.
Input
The voltage sense terminals must use a wire gauge
of 16 to 14.
