Selection Notes

The PS407 4 A runs directly from 120/230 V AC or DC mains without a separate 24 V DC source, which makes it the choice when the installation only has AC or DC line power at the rack rather than a regulated DC bus. Its 4 A backplane-bus rating suits a lightly loaded single-segment rack; choose the higher-current wide-range variant when the combined 5 V DC module load exceeds 4 A.

Applications

Its 47 to 63 Hz frequency tolerance and dual 120/230 V AC or DC rating let the same unit run on either voltage without rewiring, useful where a rack ships to sites with different mains standards. Compliance with IEC 61000-3-2 and IEC 61000-3-3 limits its harmonic current draw on the AC supply.
