Local and Remote Sensing
TM-F2OP-C1XN-01 2-23
Using Remote Sensing
Use remote sensing during voltage mode operation to shift the power
supply’s regulation point from its default position at the rear panel output
terminals to the load or distribution terminals by using a separate pair of
wires to allow the control circuitry to monitor the load voltage. This
allows the power supply to compensate for voltage losses in the load lines
which will otherwise degrade the regulation of the supply. Line drop is
subtracted from the voltage available at the power supply's output.
To connect remote sense lines:
1. Turn OFF the power supply.
2. Remove the local sense jumpers connecting J10 mating connector
terminal 5 (positive sense) to terminal 4 (positive output) and
terminal 1 (return sense) to terminal 2 (power supply return).
3. Connect the positive remote sense lead to J10 mating connector
terminal 5 (positive sense) and the negative lead to terminal 1 (return
sense). Ensure that the mating connector is plugged securely into the
rear panel sense connector. Connect the other ends of the sense wires
to the corresponding sense points at the load.
WARNING: Shock hazard
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.
WARNING: Shock hazard
Ensure that the chassis ground screw does not penetrate more than 3/8 in. (9 mm)
into the rear panel of the unit.
CAUTION
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.
CAUTION
Do not use remote sensing with multiple supplies connected in series.
