4. Input Inrush Current

The power supply 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 usually smaller than the steady state input current.

5. DC Input

Do not operate this power supply with DC input voltage. Check the 1606-XLE480EP-D unit instead.
Two 1606-XLE480EP-D units in parallel might be necessary.
