The IEC 62368-1 Knowledge Hub covers an exceptionally wide range of topics, which we believe can be helpful to manufacturers and distributors of A/V & ICT equipment.
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: UL has the answer.
Q&A: List of articles with IEC 62368-1
If a product is using a power supply certified to IEC 60950 or IEC 62368, with direct connection to the appliance mains inlet, does the 'Stored discharge on capacitors' test of 5.5.2.2 still have to be done?
As for the IEC62368-3:2017, the test methods for specified ports (USB or PoE) under different conditions are not clear. Will these parts be clarified?
How to understand the highest and lowest specified charging temperature in Annex M.4.2? Can we regard the "charging operation temperature" in the battery specification like 0 -45 degree C as these two temperatures?
Could you explain more details about Annex K.7.1? Especially for the first 4 paragraph? In actual practice, the interlock switch used in mains circuits hardly have 3mm contact gap. what should i do for this case?
Related to hiccup mode, how are power sources classified per 5.2.2 for a 3.6 V output?
Which are the temperature limits during the abnormal operating conditions?
According to IEC60950-1, Chapter 5.2 Electric Strength, Table 5B, the test voltage is 1500VAC for a device with basic insulation and 230VAC operating voltage. Where can I find this test voltage for such a device in IEC62368-1?
IEC62368-1 has three methods for determining the electric strength test voltages. Those are explained in sub-clause 5.4.9.1. As stated, the highest value calculated…
If we have a product that its output 3.3V SELV, 16 W (more than 15W) or PS2 energy that meets Table Q.1 requirements. Does the power need to be contained?
When can my company begin submitting AV & ICT equipment and components for product investigation and certification to Edition No. 3 of IEC 62368-1?
What are the key differences between the existing Edition No. 2 of IEC 62368-1 and the recently published Edition No. 3?
Given that the 2nd edition is more onerous, what is the likelihood of an agency such as UL allowing a 3rd edition relaxation in their 2nd edition certification?
It'™s an oversimplification to state that Ed 2 is more onerous than Ed 3. A better way to view it is that Ed 3 has incorporated some refinements into it that…
