Local and Remote Sensing

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-
11 for a drawing of the sense connector.
Sense Wiring
For lowest noise performance, use shielded pair wiring of 16 to 24 AWG
for remote sense lines. Strip wires 0.26 in. (6.5 mm) and insert securely as
with any wire clamp connector.
Local Sensing
We ship the power supply with the rear panel J10 sense connector
jumpered for local sensing of the output voltage. See Table 2-5 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 precise 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.
WARNING: Shock hazard
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 model 600 V, 4 A power supply. Ensure that
connections at the load end are shielded to prevent contact with hazardous
voltages.
