4.7 Remote Sensing
In applications where the load is located some distance from the power supply, or the voltage
drop of the power output leads significantly affects load regulation, remote voltage sensing may
be used. When remote sensing is used, voltage is regulated at the load versus the power supply
output terminals. To connect the power supply for remote voltage sensing (see Figure 4-8
for
connection requirements), perform the following procedure.
Connect sensing leads from the load positive to REMOTE SENSE CONNECTOR Positive and the
load negative to REMOTE SENSE CONNECTOR Negative. A shielded, twisted-pair, hookup wire
is recommended to avoid potential noise interference. Use red wire for the positive sense, black
wire for the negative sense.
WARNING: The following conditions should be avoided, as they will damage the power supply
and any warranty will be voided:
Opening the sense connection while power is applied. This will cause the output voltage
to shoot past the maximum voltage. (Open loop condition).
Reversing positive and negative sense connections (reversed polarity).
Shorting the external sense wires while power is applied. This will cause the output
voltage to shoot past the maximum voltage. (Open loop condition).
Disconnecting one or both of the load connections using a breaker or switch but leaving
the external sense connections in place while power is applied. This will cause the output
voltage to shoot past the maximum voltage and may damage the sense circuits. (Open
loop condition).
