Sense" Function - Conrad Electronic VOLTCRAFT SPS12/120 Operating Instructions Manual

9. "SENSE" function

The switching power supply features an automatic voltage control for the high-current 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 compensates for this potential drop
automatically so that the voltage on the consumer remains as set.
Proceed as follows for connection:
1. Always connect the DC connection cables from the power supply to the consumer first. Ensure the polarity is correct.
2. Press the terminals on the "SENSE" connection (9) inwards with a small screwdriver and insert the cables into the
terminal openings. Check that they are plugged in firmly.
3. 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
4. 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.
