f) REMOTE control (only SPS 1560 PFC)
Through the built-in "REMOTE" control connection, the voltage setting can take place with an external voltage source
or through an externally adjustable resistance (short "poti") and it´s possible to switch the DC output on/off.
The REMOTE connection takes place on the rear REMOTE built-in plug (14).
Preparation of the remote control connection.
1
1. Turn the central screw of the supplied slide-in jack and remove the front, black contact jack by means of a small
turning movement.
2. Draw the five connecting cables with a conductor cross-section of at least 22AWG (=0,34 mm
sleeve from the rear. Solder these five cables firmly and carefully to the soldering lugs no.1,2,3,7 and 8 of the
black contact jacks.
3. Mark the loose ends of the cables with the corresponding contact numbers (1-3) to rule out any confusion.
4. Insert the black contact jack in the reverse order into the metal sleeve and screw these firmly.
Control through external voltage source
2
The power unit can be remote-controlled by means of an external voltage source of 0 to 5V/DC over the complete
output voltage range.
Proceed as follows for connection:
1. Connect the connecting cable of the REMOTE plug as illustrated.
- Connection 2 to the plus pole (+) of the voltage supply and connection 3 to the minus pole (+) of the voltage supply.
- Connection 1 is not required.
