Notes from the Secretariat

Welcome to the winter 2016/17 edition of the EPSMA newsletter.

2017 has started with more global upheaval with the results of the US elections. Along with ‘Brexit’ there could be major implications for trade with European power supply manufacturers. The EPSMA is monitoring events and will work to protect the interests of members.

Please keep a flow of marketing information about your products, news and vacancies coming to the secretariat for placement on the website. It’s free!
Also remember 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

As ever, meeting minutes and committee reports are in the members’ area of the website. Contact the secretariat if you need your password re-sending.

February management committee meeting

Hosted at Delta offices in Hoofddorp the Netherlands on the 8th February,

nine management committee members attended and were shown great hospitality by Delta. Members were given a tour of the Delta building ‘energy management system’ showcasing technology that saves energy and money.

Technical Committee  

Paul Conway, technical committee chairman, reported good progress with updates to the popular EPSMA technical documents on CE marking and ‘Power Factor Correction’. Work is also being done to extend the scope of the ‘Accurate Efficiency Measurements’ white paper to include 3-phase systems and inverters. The paper is current number 1 hit on Google, Yahoo and Bing when searching for this subject.

The technical committee has noted a new standard published by the US Department of Energy for ‘Energy conservation standards for battery chargers’ . This may adversely affect some EPSMA members and representations to the DOE are being considered. See this page in the members’ area of the website for more details

Website Update

Links to EPSMA members’ recruitment sites have been added.

More information is accumulating on standards and compliance and energy efficiency in the members’ area.

A refresh of the ‘look’ of the website is being considered

UL-508 to UL-61010 transition

EPSMA members have expressed concern about the transition. While
UL-61010 is a more relevant, modern standard, there are some issues which require clarification, particularly the conditions under which power supplies may be allowed to operate at more than 50% loading. Work is to be done to collect a summary of concerns which will be presented to UL on behalf of the EPSMA members.
