The sum of the configured output power of all outputs can exceed the total output power. In
this case, the outputs switch off one after the other in reverse order (OUT4, OUT 3, …) until the
total output power is within the permissible range again. The lower output in each case re-
mains switched on to prevent voltage dips and to output current continuously.

After having been switched off, the outputs start automatically one after the other at intervals
of 150 ms in the sequence OUT1…OUT4.

Hold-up time
The hold-up time is the time during which a power supply’s output voltage remains within spe-
cification following the loss of input power. The hold-up time is output load dependent. At no
load, the hold-up time can be up to several seconds. The status LED is on during this time.
