We use a couple different 24VDC power supplies to drive testing instrumentation we manufacture. Recently we've been told that using a supply with "Automatic" voltage inputs (120V/230V) puts our equipment at risk when used on a 230V circuit and one leg drops, causing an "under voltage" situation, blowing up critical components because the supply cannot switch back to 120V fast enough. We have never experienced this and never had any of our international customers report this problem.
I am aware that power supply manufactures do make 120V or 240V input power supplies, but I am unsure as to what applications these apply to and cannot find any information pertaining to the above scenario.
Any help is appreciated.
