Connecting outputs in parallel Yes, max. 4 × 2 outputs each that must lie next to one another.
Switching on outputs All outputs are switched-on after the supply voltage ramps up
> 20 V, delay time of 25 ms, 200 ms, 500 ms – or "load opti-
mized", selectable using DIP switch.
Shutdown characteristics:
Figure 6-1 Shutdown characteristic
The following applies for the SEL1200: In the range > 150 %, a higher current is briefly
permitted; afterwards it is shut down corresponding to the "Shutdown characteristic"
diagram.
