What is the difference between remote and local sense?
Local Sense involves using the power supply output power terminals as the sense points to provide feedback to the internal voltage regulation circuitry. Remote sense involves detection of output voltage at a point remote from the power supply, enabling the power supply to regulate output voltage and to compensate for voltage drop typically associated with long power cables. This permits greater accuracy of regulation than local sensing. The sense connections (from the sense pins) determine the regulation point, either at the converter output (local sense) or at the load (remote sense) to compensate for voltage drop. It is important to “close” the sense lines, i.e., +S to +Out, -S to Out, as described above for proper operation of the module; and it is an absolute MUST for Maxi and Mini modules.
