Re: [PSES] EMC requirements for Korea

You'll need translation of some documents, but the test house I use provides that as well. From: Robert Dunkerley [mailto:robert.dunker...@snellgroup.com] Sent: Friday, August 21, 2015 1:25 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] EMC requirements for Korea Hi all, Thanks for the

Re: [PSES] 2014/35/EU Requirement for Postal Address

A suggestion - if your company name, city and state, are already on the label or nameplate, ask your local postal facility if that is sufficient for mail to be delivered to your company. This came up with a firm I used to work for many years ago and when asked the local post office said that

[PSES] New EMC Directive 2014/30/EU LV Directive 2014/35/EU

Hi All, The captioned directives will be enforced on 20 April 2016 with no transition period. As of today, no accredited laboratories accept the compliance verification to those directive until 20 April 2016. They claim they cannot test to those directives until 20 April 2016 as per the

Re: [PSES] New EMCD DoC Requirements

So let's tackle this one example, for now. Annex IV point 8 says, 8. Additional information: Signed for and on behalf of: (place and date of issue): (name, function) (signature): So the text, Signed for and on behalf of: is required no matter who signs the DoC or is it only required if the

Re: [PSES] Different surge test equipment, different results

David - Thank you. In one case, the output was after the CDN. In the other, the CDN was not in the circuit. I will ask for calibration screen captures with and without the CDN on both cases. This could prove informative. Regards, Peter Tarver -Original Message- From: Schaefer,

Re: [PSES] Different surge test equipment, different results

Peter, Are the open circuit waveforms identical out of the surge generator, or out of the coupling decoupling network? -4-5 relaxes the waveform limits for the rise time and duration at the output of a CDN, based on amperage. Check out tables 6 and 7 of the 2nd Edition for more information.

[PSES] Different surge test equipment, different results

Good morning. I'm wondering if others have experienced cases where different manufacturers' surge test equipment (ANSI/IEEE C62.41 ring and combination waves) with nearly identical open-circuit voltage and short-circuit current calibrations have led to very different results. In these cases,

Re: [PSES] New EMC Directive 2014/30/EU LV Directive 2014/35/EU

Scott Test labs should test to standards. Manufacturers declare to compliance to Directives. The two beams should not cross :) You won't get anything officially, but unofficially the EU MSAs and enforcement agencies should take a pragmatic stance regarding DoCs and not be too concerned whether

Declarations, test reports, etc are part of a contractual law system, so this will reference the legal point of view, and as am not a solicitor or attorney, you should to talk to the one retained by your employer. 'for and behalf of' relates to the term 'procuration' - essentially a proxy by

[PSES] EMC test lab, New York

I’m looking for recommendations for EMC testing services for a client in New York state. I need a well equipped lab which charges by the hour, properly understands the EMC Directive, has a good technical understanding of the EN standards and can recommend solutions in the case of minor

Re: [PSES] Different surge test equipment, different results

Thanks David for bringing that detail into focus. Edition 2 writes about unwanted voltage drops from coupling/decoupling networks, while Table 6 allows for a shorter front time for higher line currents, presumably to reduces impedance required by the decoupling network ( a smaller

Re: [PSES] 208V/30A/3PH NEMA 3R power distribution question

Adam – Brian’s suggestion I a good one. Answer from electrician should include three 20 A, two-pole branch circuit breakers for each single-phase load, possibly one main 45 A, three-pole breaker (with dependencies), plus Neutral bar (if needed) and ground bar. Miscellaneous assorted

Re: [PSES] New EMC Directive 2014/30/EU LV Directive 2014/35/EU

Hi Charlie, Thanks for sharing the temporary solution. For the products that compliant with current directives, are they just updated the DoC to comply with the new ones? What about the RED replacing RTTE? This one cannot be simply updated the DoC since all the receivers will fall into RED

Re: [PSES] EMC requirements for Korea

Hi all, Thanks for the info. It would be ITE, so I guess KN22/KN24. Under my understanding, these are almost identical to EN55022/EN55024, apart from: -radiated emissions must be tested at 10m, not extrapolated data from 3m - a mains supple of 220V/60Hz must be used - emissions at
