Does any industry have a 100VDC power bus?

Hello,

I cannot understand why these xenon flash beacons are designed to run off an input voltage of 10-100VDC.

Surely very very few industrys uses a power bus of 100VDC?


I woudl have thought 60VDC was the maximum likely to be used, otherwise they would just use 230VAC or 120VAC mains... or even 3 phase mains (415VAC)?
 

Telecom is 48V, and some applications impose voltage
deratings of 2X when reliability is needed "by the book".
10V meanwhile is a discharged automotive battery.

Probably just trying to cover as many apps with one
design, as practical.

thanks.....the thing is that above 60V and the cost of solutions goes up dramatically...because there are few monolithic led drivers, IC's etc which can handle above 60V.
