Connection of remote sense
•
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. Recommendation for cables up to 5 m
(16.4 ft): use at least 0.5 mm²
•
Sense cables shouldn’t be twisted, but laid close to the DC cables, i. e. Sense- cable close
to DC- cable to the load etc. to damp or avoid possible oscillation. If necessary, an additional
capacitor should be installed at the load/consumer to eliminate oscillation
•
The Sense+ cable must be connected to DC+ on the load and Sense- to DC- at the load,
otherwise the sense input of the power supply can be damaged. For an example see Figure
11 below.
•
In master-slave operation, the remote sensing should be connected to the master unit only
•
The dielectric strength of the sense wires must always at least match the DC voltage rating!
