Remote sensing is used to compensate for the voltage drop that
occurs across the wires connecting the source to the input of the
Active Load modules. A separate pair of wires is routed to measure
the voltage at the source terminals where precise measurement of the
output voltage is desired.
The remote sense leads are connected at the DC INPUT connector
on the front panel of the modules. Refer to the section, DC Inputs, for
information on connector pinout. Connect the SNS terminal to the load
terminal connected to the module DCIN terminal, and the SNS-RTN
terminal to the load terminal connected to DCIN-RTN terminal.
Special care is required in routing the sensing leads to prevent noise
pickup or coupling to the power leads; refer to the section, Noise and
Impedance Effects. The sense leads should be a twisted-pair of AWG
#16-20 wire, and may require shielding in high noise environments.
Connect the shield to the shield ground terminal, CHAS-GND, of the
DC INPUT connector, as required to maximize its effectiveness.
