Configure overload switch-off
You can configure the overload switch-off for each output voltage individually.
The configuration of the overload switch-off is similar to the selection of a fuse: you select the nominal current and the tripping characteristic.
The nominal current can be set between 1000 and 3000 mA.
Port | Nominal current in mA | Tripping characteristic |
|---|---|---|
X52 | 8000:12 "Nominal Current Us" 8000:13 "Nominal Current Up" | 8000:11 "Characteristic" |
X53 | 8010:12 "Nominal Current Us" 8010:13 "Nominal Current Up" | 8010:11 "Characteristic" |
X54 | 8020:12 "Nominal Current Us" 8020:13 "Nominal Current Up" | 8020:11 "Characteristic" |
X55 | 8030:12 "Nominal Current Us" 8030:13 "Nominal Current Up" | 8030:11 "Characteristic" |
If the nominal current is exceeded, the status bit "Warning" is set.
Examples of the switch-off time
The following table shows the switch-off time of the overload switch-off for different currents and tripping characteristics.
 | Shorter switch-off time with 5 A current limitation The switch-off times shown only apply to output currents below 5 A. At 5 A, the starting current limitation limits the output current and switches it off after 75 ms, even if the switch-off time of the overload switch-off would be longer. |
