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 automat
-
ically and regulates the output voltage (only in CV operation) at the load rather than at its own DC output.
In the technical specifications (see section
„1.8.3. Specific technical data (400 V AC models)“
) the level of maximum
possible compensation is given. If that is insufficient, the cable cross section must be increased.
Both pins „NC“ of the Sense connector must not be wired!
•
Remote sensing is only effective during constant voltage operation (CV) and for other regulation
modes the sense input should be disconnected, if possible, because connecting it generally
increases the oscillation tendency.
•
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 (16.4 ft) 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 con to + and - to - at the load, otherwise both systems
may be damaged
