Connecting A Consumer; E) "Sense" Function (Only Sps 1560 Pfc) - VOLTCRAFT SPS 1525 PFC Bedienungsanleitung

Only change the setting when no consumers are connected! Verify the operating voltages of the consumers first!
d) Connecting a consumer
1. Make sure the consumer is switched off.
2. Verify that the correct output voltage has been set.
3. Connect the plus pole (+) of the consumer to the red terminal screw connector "+" (4), and the minus pole (-) of the
consumer to the black terminal screw connector "-" (3).
4. 4-mm standard connectors can be used for connection but should take place via 20 A by means of screw terminals.
(the jack heads can be screwed on to the front only for the SPS 1525/1540 PFC!).
5. For the switch power unit SPS 1560 PFC up to 5A can be connected at the front safety-jack consumer (automatic
current limit) and up to 60A at the rear through high-current terminal jacks.
6. The power consumption of the connected consumers is shown on the current display (8).
Make sure that the consumers are switched off when connected to the switched-mode mains power supply.
Sparks may be generated when a consumer which has been switched on is connected to the jacks. This
may damage the terminal screw connectors as well as the connected cables.

e) "SENSE" function (only SPS 1560 PFC)

The switched-mode power supply possesses 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 switched-mode power supply compensates this
potential drop automatically so that the actually set voltage is pending on the consumer.
Proceed as follows for connection:
1. Always connect the supply cables from the power unit to the consumer. Pay attention to correct polarity.
2. Press the orange-coloured terminal on the SENSE connection inwards with a small screwdriver and insert the
cables into the green terminal openings. Check that they are plugged 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 22AWG (= 0.34 mm
4. Always slacken the connection in the reverse order (first of all the "SENSE" cables and then the connecting cables).
Make sure that you contact the SENSE cables as close as possible to the connecting point of the consumer.
Never short the "SENSE" cables.
