Connection of remote sensing
•
Both pins „NC“ of the Sense connector must not be wired!
•
Mind the electric strength of the sense cables, especially with models of ≥ 500 V rating!
•
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 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
•
In master-slave operation, the remote sensing should be connected to the master unit only
