Operating Instructions, 06.2013, C98130-A7599-A1-2-7629
The device supplies a constant output voltage until the current limit is reached. In the event
of an overload, the output current and the output voltage are reduced. When the output
voltage falls below approx. 9 V (12 V versions) and 15 V (24 V versions), the device switches
off, and automatically restarts. This response is repeated as long as the overload condition is
present.
