Connection of remote sensing
•
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 os-
cillation 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 14 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!
Dangerous voltage on the sense connectors! The sense cover must always be installed.
