[PSES] Call for Papers - 2016 IEEE 20th Workshop on Signal and Power Integrity (SPI)

Dear Members, The 2016 IEEE 20th Workshop on Signal and Power Integrity (SPI) will be held from May 8 to May 11, 2016 in Turin, Italy. On behalf of the SPI 2016 Standing Committee, it is my pleasure to invite you and your colleagues to contribute papers, talks, exhibitions to the event. Over the

Hi Ron: >But, a capacitor charged to such an open-circuit voltage need to also be rated for that voltage (probably a DUH moment). Correct? Yes. >Is Table 2 of IEC 61201:1992 equivalent to Table A.2 of IEC 61201:2007? Yes. >ECMA 287 Table 3.4 ES1 values decrease from 60

Re: [PSES] EN 62368-1 query

Hi Ron: The values in Table 5 are taken, directly, from IEC 61201, Table A.2 and Figure A.1 (notes 1 and 2). See Annex A, IEC 61201, for further information about these values. Upeak is not the correct term; the voltage is the open-circuit voltage to which the capacitor is charged.

[PSES] EN 61000-3-3:2013

EN61000-3-3 is transitioning from the 2008 to 2013 next June. Has anyone gone through this and identified any major changes since the 2008 edition? Is a retest in order for existing equipment? Regards, Mike - This message is

Re: [PSES] EN 62368-1 query

Hi Rich, Thanks for your reply. And, neither would I be in line to be a guinea pig for that, but that does remind me of the opening scene in Ghostbusters. :) But, a capacitor charged to such an open-circuit voltage need to also be rated for that voltage (probably a DUH moment). Correct? I

Hi Rich, Thank you for your patience. Acknowledged on my choice of wording. No more clarification need on this. Thank you. Best regards, Ron Pickard Regulatory Compliance Engineer Compound Photonics D | +1 (602) 883-8039 From: Richard Nute [mailto:ri...@ieee.org] Sent: Monday, October 26, 2015

[PSES] EN 62368-1 query

For all those more familiar than I with this standard, I would appreciate a clarification. I've just purchased EN 62368-1 (assuming IEC 62368-1, too) and have started immersing myself in it, but in 5.2.2.3 (Table 5) ES1/ES2 voltage limits from a charged capacitor appear to violate the ES1/ES2

Re: [PSES] 208 split-phase?

Ralph – I’m less familiar with the CEC, but the NEC does not preclude 208/120 V WYE to a single-family home (residence). It all depends on how much one is willing to pay the utility for the service and proper provisioning and system design at the use location. Peter Tarver *From:*

Re: [PSES] EN 62368-1 query

Hi Ronald, It may be helpful for you to purchase a copy of 62368-2, which has the rationale for the requirements in 62368-1. Others can provide more detail and probably explain better than I, but in general Table 4 has voltage *or* current limits, and Table 5 has capacitance *and* voltage
