Input Inrush Current
The power supply unit is equipped with an active inrush current limitation
circuit, which limits the input inrush current after turn-on to a negligible low
value. The input current is smaller than the steady state input current.
DC Input
Do not operate this power supply unit with DC-input voltage. Use the
1606-XLE480FP-D unit instead. It can be necessary to run two
1606-XLE480EP-D units in parallel.
