Summer 2024

Notes from the Secretariat

In this summer newsletter we report on changes to the management of the EPSMA and efforts to influence the IEC with its proposed ruling on PSU derating at low mains - a subject which will have major implications for manufacturers worldwide.

EPSMA MC meeting May 7th 2024

The management committee meeting was held by conference call with good attendance - 14 members and guests.

This is the last meeting organised by Paul Lee who is stepping down from managing the secretariat. Replacement  Jonathan Pieterse will take over from now. Actions are in hand to transfer control of EPSMA finances, website and general organisation to Jonathan.

The issue of the IEC proposing that derating of AC-DCs at low mains be disallowed in safety certification with immediate effect has progressed, with committee TC108 acknowledging the EPSMA and ZVEI objections and offering to consult further. The EPSMA has set up a working group along with ZVEI to liaise with the committee.

The EPSMA notes that the UK has now made law the need to provide and show cyber security precautions in network-connected consumer and telecommunications products. It is not clear how this affects industrial power supplies with network connections but information indicates that the requirements are 'common sense' and EPSMA members are likely to be already compliant. We will continue to monitor and record member experience with the legislation.

The EPSMA technical committee will now proceed with work on a document providing guidance on the application of EMC standards and a next proposed project is a document describing how to evaluate lifetime carbon footprint of power products.

Meeting minutes and slides will be available to members on the EPSMA website shortly

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.
