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 load regulation is not essential.
Important:
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.
