Another way to use them is to switch a series resistor
out of the power supply input after a few seconds; that is good for capacitor-input
filters where the inrush current is otherwise very high. The 5 second delay may be just
that; it seems a bit short for the pre-heat delay.

That works nice for both audio and digital power supplies.
One can add a relay to latch the output after the time delay, as well as
turn off the power to the time delay.
5 seconds sounds good for a core memory power supply.
