10.6.1 “Constant Current” Mode
In this mode, the load current on the output is limited if the nominal output current is ex-
ceeded by a significant amount. The load current is limited to about 110 % of the nominal
output current. This occurs for 20 seconds.
If the overload lasts longer, a 15-second pause occurs, during which the output voltage is
switched off. The output voltage is then switched back on. If the overload is still present,
the process starts again.
This mode is set by default.

ceeded by a significant amount. The load current is limited to about 110 % of the nominal
output current. This occurs for 20 seconds.
If the overload lasts longer, the output is switched off. To switch the output back on, man-
