2.3.6 Connection of remote sensing
In order to compensate, to a certain degree, the voltage loss in a DC cable, the device provides the possibility to
connect the remote sensing input “Sense” to the load. The device recognizes the remote sensing mode automati-
cally and regulates the output voltage (only in CV operation) at the load rather than at its own DC output.
Inthetechnicalspecications(seesection „1.9.3. Specic technical data“) the level of maximum possible com-
pensationisgiven.Ifthatisinsufcient,thecablecrosssectionmustbeincreased.
Both pins „NC“ of the Sense connector must not be wired!
• The cross section of the sense cables is noncritical. However, it should be increased with
increasing cable length. Recommendation: for cables up to 5 m use at least 0.5 mm²
• Sense cables should be twisted and laid close to the DC cables to damp oscillation. If neces-
sary, an additional capacitor should be installed at the load/consumer to eliminate oscillation
• The sense cables must be connected + to + and - to - at the load, otherwise both systems
may be damaged
