Local and Remote Sensing

Local and Remote Sensing
Use connections on the rear panel J2 connector to set up the power supply for local
or remote sensing of output voltage.

regulated at the output terminals. This method does not compensate for voltage
losses in the load lines, so it is recommended only for low current applications or for
applications in which load regulation is not essential.
Note: When using local sense connections, use the largest practical wire size to
minimize the effects of load line impedance on the regulation of the supply.

Note: Ground the sense line shield in one place only. Locations include: the power
supply's return output connection at the load, the power supply's return output at its
negative output terminal, or the power supply's chassis.

WARNING
There is a potential shock hazard at the sense connector when using a power
supply with a rated output greater than 40 V. Select wiring with a minimum
insulation rating equivalent to the maximum output voltage of the power supply
for use as local sense jumpers or for remote sense wires. For example, select
TEW-105, 105 °C, 600 V wiring for use with a 600 V, 1.7 A power supply. Ensure
that connections at the load end are shielded to prevent contact with hazardous
voltages.

WARNING
There is a potential shock hazard at the sense points when using a power supply
with a rated output greater than 40 V. Ensure that connections at the load end
are shielded to prevent contact with hazardous voltages.
CAUTION
!
Do not use remote sensing with multiple supplies connected in series.
