Hi Chuck:
I have reviewed the IEC draft version of EN 62368-3, 108/639/CD. As near as I can tell, the power limits depend on the components of the system such as wire size and connector ratings. In some cases, the power can be as high as 100 watts. In other cases, the current is limited to 1.3 amperes. There is no one answer to your question. Best regards, Rich From: Chuck August-McDowell [mailto:[email protected]] Sent: Wednesday, March 08, 2017 1:49 PM To: [email protected] Subject: [PSES] EN 62368-3:2017-02-15 power limits Greetings from Berkeley, I am curious to know the power limits described in the draft standard EN 62368-3:2017-02-15.
