Please have a look on CISPR 11 Clause 6.2.1.1, quote: “The limits for the LV d.c. power port specified hereafter apply only to grid connected power convertors…”
The 61326-1 and 60601-1-2 refer to CISPR 11 as whole (“limits, measuring methods and provisions given in CISPR 11 apply” and “shall comply with CISPR 11”) so you use the same classification. I hope this helps, with best regards, Ari Honkala From: Paolo Roncone [mailto:paoloc...@gmail.com] Sent: maanantai 28. marraskuuta 2016 11:25 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] DC-power conducted emissions per CISPR11: 2016 Hi all, the new 2016 edition of CISPR11 requires DC power ports conducted emissions to be done with a "150 Ohm CISPR Delta-network (DC-AN) – see CISPR11 ed.6.1 (2016) sec. 6.2.1.3, 7.3.2.3 and Annex I) instead of a "standard" 50uH/50ohm V-LISN, used for AC-power conducted emissions and also for AC&DC power conducted emissions according to IEC/EN 61000-6-3, CISPR22 and other standards. That means - to my understandiing - that DC-powered Laboratory equipment (tested per IEC/EN 61326-1, sec. 7.2) and Medical devices (tested according to IEC 60601-1-2 (sec.7.1.1) must be tested with the Delta-LISN for DC-power conducted emissions. Is my understanding correct?
