Sometimes power supplies have USB and RS232 interfaces, what is the reason?

edit

In this video of eev blog, david jones was doing a teardown of one which has rs232 and usb interfaces..

    \$\begingroup\$ Suppose you make a product and your datasheet says it works at 5 V +/- 10%. How would you imagine testing that capability? Suppose you have to test 100 (or 1000) units per hour? \$\endgroup\$ – The Photon Oct 30 '16 at 16:01

This would typically be to allow them to be remotely programmable from a PC, e.g. this TDK-Lambda Z+400 supply which provides USB, RS-232 and RS-485 interfaces.

Programmability is very useful in setting up automated testing. Sort of like having a DAC with a large current capability.
