2.3 Potentiometer
SITOP PSU300S
12 Manual, 12.2016, C98130-A7587-A1-7-7629
The potentiometer ③ at the front of the device is used to adjust the output voltage. The
output voltage is set to 24 V in the factory, and can be adjusted in the range 24 - 28 V; for
example, to compensate voltage drops across long supply lines to the connected load.
Figure 2-5 Potentiometer (example 6EP1437-2BA20)
Thermal overload possible
When adjusting the output voltage to >24 V, 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
for 6EP1433-2BA20 and 6EP1434-2BA20 (Page 10), Figure 2-3 Terminal data for 6EP1436-
2BA10 (Page 10) and Figure 2-4 Terminal data for 6EP1437-2BA20 (Page 11)
