Sense" Function - VOLTCRAFT SPS12/120 Notice D'emploi

"SENSE" function

The switching power supply features an automatic voltage control for the high-cur-
rent output. For this, two separate measuring cables are connected parallel to the
connecting cables. The potential drop which occurs on the connecting cables is
measured on these two measuring cables. The switching power supply compensa-
tes for this potential drop automatically so that the voltage on the consumer remains
as set.
Proceed as follows for connection:
• Always connect the DC connection cables from the power supply to the consumer
first. Ensure the polarity is correct.
• Press the terminals on the "SENSE" connection (9) inwards with a small screwdri-
ver and insert the cables into the terminal openings. Check that they are plugged
in firmly.
• Now connect the two "SENSE" cables to the consumer observing the correct
polarity. The conductor cross-section for the "SENSE" cables must be at least
0.34 mm 2 (= 22 AWG).
• Always remove the connections in the reverse order (first of all "SENSE" cables and
then the DC connection cables).
Ensure that the "SENSE" cables are contacting as close as possible to
the connecting point of the consumer.
Never short the "SENSE" cables.
