UPDATE: 62368 Clause 5.2.2.5 states that voltage cannot go over 42.4Vpk if less than 3secs. So, does this mean in hiccup mode the output cannot go over 42.4Vpk? Therefore a 48V output will not pass to ES1? This is different to 60950.
It is understood you are asking, “What are the ES1 voltage limits when a power supply goes into a hiccup mode (repetitive peaks) i.e., pulse off time less than…
