Get the hard facts to a successful transition – from your UL experts
The IEC 62368-1 Toolkit covers an exceptionally wide range of topics, which we believe can be helpful to manufacturers and distributors of A/V & ICT equipment as you plan your transition.
This Q&A includes many of the questions we have been asked, with answers from UL experts. Registered users may also submit additional questions related to the 62368 transition: UL has the answer.
Q&A: You ask, we answer

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…
