Potentiometer

The potentiometer
output voltage is set to 12 V, 24 V or 48 V in the factory, and can be adjusted in the range
12 ... 14 V, 24 ... 28.8 V or 42 ... 56 V; for example, to compensate voltage drops across long
supply lines to the connected load.
Figure 2-4
NOTICE
Thermal overload possible
When adjusting the output voltage to >24 V (>48 V), the output current must be derated by
4 %/V or the permissible ambient temperature must be taken into account with 3 K/V
(applies to PSU300M devices).
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 6EP1436-3BA10, 6EP1456-3BA00, 6EP1424-3BA00, 6EP1436-3BA20 (Page 10) and
Figure 2-3 Terminal data for 6EP1437-3BA20 (Page 10).
