Brent, It has been our practice in the past to perform all Domestic EMI (FCC) testing with the unit operated at 115V/60Hz. We perform all European EMI and EMC testing at 230V/50Hz. The only exception are devices which are shipped with separate power supplies for each European country (such as separate wall adapters), in which case the unit must be tested at the power supplies rated specifications. I hope this helps!
I happen to know of several accredited test labs who offer the same power capability - 115/60 or 230/50. - Randy Flinders EMC Test Engineer Emulex Network Systems ---------- From: owner-emc-pstc To: rflinders; EMC-PSTC Subject: EMC Test Voltages List-Post: [email protected] Date: Thursday, April 24, 1997 12:18AM Return-path: <[email protected]> List-Post: [email protected] Date: 24 Apr 97 00:18:51 EDT From: Brent Taira <[email protected]> To: EMC-PSTC <[email protected]> Subject: EMC Test Voltages Message-Id: <[email protected]> Sender: [email protected] Precedence: bulk Reply-To: Brent Taira <[email protected]> X-Resent-To: Multiple Recipients <[email protected]> X-Listname: emc-pstc X-List-Description: Product Safety Tech. Committee, EMC Society X-Info: Help requests to [email protected] X-Info: [Un]Subscribe requests to [email protected] X-Moderator-Address: [email protected] ---------------------------------------------------------------------------- -- Dear Group, I have a simple inquiry concerning the appropriate test voltages and frequencies to be used during the various EMC Tests. 1) What are the appropriate voltages to be used for FCC Testing (Class B)? 90V, 100V, 110V, 115V, 117V, 120V? How about frequency? 2) Same question for CISPR22? 200V, 220V, 230V, 240V, 254V? Frequency? 3) Same for VCCI, except then you get into ....100V and 200V. Frequency? 4) Now, EMC. Same questions. Theoretically, you would want to test for all possible voltages and frequencies that your product is intended to support. What has been the common practice in your company/lab/country? Thank you in advance for your time, Brent Taira
