What to do if you are not using the remote sense feature
In cases where the remote sense feature is not used, the remote sense lines should not be left open for optimum load regulation; instead, a local sense configuration should be set up.
To set up a local sense circuit, the +ve and –ve sense lines should be either:
1. Connected to their corresponding local sense (LS) terminals, which are provided on many power supplies
2. Connected to their corresponding +Vout and –Vout terminals.
Most power supplies are shipped from the factory with local sense jumpers installed on the power supply, see red and black jumper wires on left image, or with sense screw terminals connected to the output screw terminals with metal jumpers, as shown on the right image.
