Control through a controllable resistance (poti)
The power unit can be remote-controlled by means of an external poti of 5 KOhm
over the complete output voltage range.
Proceed as follows for connection:
Connect the connecting cable of the REMOTE plug as illustrated.
Connection 1 at one end of the resistance.
Connection 2 at the centre sliding contact of the resistance.
Connection 3 at the second end of the resistance.
Switch off the switched-mode power supply and then connect the REMOTE plug to
the rear remote connection. Screw the external fastening ring.
Slide the rear VOLTAGE REMOTE
switch to the "ON" position.
Switch the switched-mode power supply on. The desired output voltage can now be
set through the external poti. Control the complete adjustment area for correct function.
If this remote control function is no longer desired, move the switch to the "OFF”
position.
Enable and disable the output
You can use Port 7 and 8 to remote control the output on/off.
Open Port 7 and 8 if you want to enable the output (default).
Short Port 7 and 8 if you want to disable the output.
Maintenance and Cleaning
The switched-mode mains power supply units are maintenance-free, apart from the
need to replace fuses and cleaning them once in a while. Use a clean, lint-free, anti-
static and dry cloth to clean the device. Do not use any abrasive or chemical deter-
gents or detergents containing solvents.
