Function and Features

3.11 Remote sense function

Remote voltage sensing is used to maintain good regulation at the load and reduce the degradation of regulation that would occur due to the voltage drop in the leads between the power supply and the load. By connecting the supply for remote voltage sensing, voltage is sensed at the load rather than at the supply’s output terminals. This will allow the supply to automatically compensate for the voltage drop in the load leads and improve regulation.

+，-： output terminal, the same as front pane output terminals.

S+,S-: Remote sensing terminal.

Disable remote sense function:

1. Use the standard shorting clip which has been installed before leave the factory. Or you can also use wires to short “S+” and “+”,”S-“ and “-“.

2. Connect output “+” and “-“ to the load input terminals “+” and “-“.

Enable remote sense function:

1. Remove the shorting clip between “S+” and “+”,”S-“ and “-“.

2. Connect output “+” and “-“(front panel) to the load input terminals “+” and “-“.

3. Connect “S+” to “+” of the load, ”S-“ to the “-“ of the load.

NOTE

To ensure the system stability, please use twisted-pair cables between sense terminal and load.
