Remote Sensing
Remote sensing permits you to shift the regulation point of the power supply from
the output terminals to the load or other distribution terminals. It compensates for
voltage losses of up to a total of 5 V in the power leads supplying the load (3 V on
7.5 V unit).
For best noise performance, use shielded pair wiring of 16 to 24 AWG for remote
sense lines.
In order to connect the sense wires, follow this procedure:
1. Using a small flat blade screwdriver, remove the two sense jumpers on the J207
connector.
2. Using the appropriate gauge shielded wire (see “Sense Wiring” ), connect one
end to the load or point at which load is to be regulated.
3. Connect the positive sense line from the load to J207-4 (+SNS) and the return or
(-SNS).
Remove default jumpers (Pins 1-2 and 4-5)
Connect sense lines as close to
load as possible or at point to be
regulated
