2.8 Local and Remote Sensing
Use connections at the rear panel J10 sense connector to configure the power supply for local or remote sensing
of output voltage. See Figure 2.8-1 for a drawing of the sense connector.
2.8.1 Sense Wiring
WARNING
There is a potential shock hazard at the sense connector when using a
power supply with a rated output greater than 40V. 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, 600V wiring for use with a model 600-4
power supply.
For lowest noise performance, use shielded-twisted pair wiring of 16 to 24 AWG for remote sense lines. Strip
wires 0.26" (6.5 mm) and insert securely as with any wire clamp connector.
2.8.2 Local Sensing
We ship the power supply with the rear panel J10 sense connector jumpered for local sensing of the output
voltage. See Table 2.8-1 for the list of connector functions and a description of local sense connections. With
local sensing, the output voltage is regulated at the output terminals (or bus bars). This method does not
compensate for voltage losses in the load lines, so it is recommended only for low current applications or
applications for which load regulation is not essential.
Note: When using local sense connections, use the largest practical load wire size to minimize the effects of
line impedance on the regulation of the supply.
