The potentiometer ③ at the front of the device is used to adjust the output voltage.
The output voltage is set to U
out rated
in the factory, and can be changed – for instance to
compensate voltage drops along long power supply cables up to the load.

NOTICE
Thermal overload possible
When adjusting the output voltage U
out rated
, the output current must be derated by 4 %/V, or
the permissible ambient temperature must be taken into account with 3 °C/V.
Note
It is only permissible to use an insulated screwdriver when
actuating the potentiometer.
For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data
