Notes from the Secretariat

It was great to be able to meet colleagues and friends face to face again at the EPSMA AGM at Electronic in Munich in November. The meeting room was sponsored by member RECOM and was well attended. We were able to approve the release of the latest EPSMA technical committee document 'Over-voltage categories and their implication in the specification of power supplies'. The document is for members only at present, but non-members can see an abstract HERE. The full document is in the members' area of the website. We may present the contents in a joint webinar with the PSMA at some future date.

The meeting also discussed issues such as UKCA marking and recent statements by UL that affect safety certification of AC-DC power supplies and could impact EPSMA members.

It was reported at the AGM that EPSMA had received notification that UKCA marking will not now be mandatory for most products until December 2024

Paul Lee for the secretariat presented accounts for the year to September 2022 which were audited at the meeting.

Member TDK Electronics gave a presentation on 'Future trends in passive components for power supplies' with a total of four speakers. The presentation was very interesting covering a novel approach to gapping ferrite E-cores for low loss and various new capacitor products were highlighted with their advantages for power applications. The presentation will be placed in the website members' area when available.

Minutes for the AGM are available in the website members' area.

After the meeting, ten members met for an enjoyable traditional dinner in Munich. See photo!

TC activities

A future project for the techncal committee proposed is guidelines for EMC standards and how they apply to power supplies. This is in the 'statement of work' phase.

Other projects suggested for the TC at the AGM include guidelines on materials issues in power products - reporting and carbon footprint calculations.


We have a ’Linkedin’ forum for members to use and a data base of UL non-conformances for members to log their observations. Contact the secretariat for more details.

CE Marking Issues forum

Remember we have a forum for issues members have with “CE” marking. If you would like to share problems (and resolutions!) With other members, please contact the secretariat with details.
