Q&A: List of articles with Clause
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…
