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 mA and 4000 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 4.4 A current limitation The switch-off times shown only apply to output currents below 4.4 A. At 4.4 A, the starting current limitation limits the output current and switches it off thermally, even if the switch-off time of the overload switch-off would be longer. |
% of the nominal current | Very fast acting | Fast acting | Slow acting | Time delay |
|---|---|---|---|---|
105 % | 3600 s | 3600 s | 3600 s | 3600 s |
135 % | 420 s | 3600 s | 3600 s | 3600 s |
200 % | 0.5 s | 20 s | 20 s | 100 s |
300 % | 0.02 s | 0.1 s | 1 s | 3 s |
