Re: [PSES] Testing a product with that uses a solar panel

The only question was: what sort of light source? For EMI concerns, incandescent works best. That¹s all there is to it. No one I know of is arguing to replace the solar array with some other power source. The power source is the luminary that illuminates the solar array, and that can and should

Re: [PSES] Testing a product with that uses a solar panel

Ken: A long time ago, I used to think there were many things that were patently obvious. As is usually the case, this question has wandered around a bit. At first, the question was whether a solar panel was really needed; couldn't the DC power be sourced from a battery or other clean DC

Re: [PSES] Intro to Safety

Frank -- There is a book that was recently published that provides a fine overview of our profession as applied to electrical products. It is titled Electrical Product Compliance and Safety Engineering, by Steli Loznen, Constantin Bolintineanu, and Jan Swart. You can see the Table of Contents

Re: [PSES] Testing a product with that uses a solar panel

Absolutely. The solar array interconnect is an antenna for both RE and RS. The point is that for RE to happen, there has to be fast switching of current as a load on the array. The array itself into a resistive load is entirely dc. Ken Javor Phone: (256) 650-5261 From: "Martin, Charles R

Ken, You mentioned "the array wiring can radiate if the current is switched fast enough", couldn't that also pick noise from other RF sources, as in Radiated Immunity? Thanks, Charlie From: Ken Javor Sent: Friday, February 15, 2019 1:09 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: EXT: Re:

Re: [PSES] Intro to Safety

Hi Frank, If you’re reading S2/S8 I’m guessing you’re in the semiconductor manufacturing equipment SME industry like I am. Welcome. You might want to see if our employeer will send you to the SEMI Standards face to face meetings at their Milpitas HQ April 1-5. You’ll meet a lot of SME EHS

Re: [PSES] Intro to Safety

Frank, There are more standards than you can ever learn. Most safety standards are written about the same way (strange, as the same risks/exposures exist across standards); it is reasonably straightforward to move between equipment safety standards. The product certification key is to pick

If you will be working on CE marked machinery then review the requirements for the technical file in the Machinery Directive. Also review requirements in the Low Voltage Directive whether machinery or not. -Dave From: Frank Tang [mailto:0d3fa4ae712a-dmarc-requ...@listserv.ieee.org] Sent:

[PSES] Intro to Safety

Hi Compliance Peers,I'm fairly new to compliance, with 4-5 years EMC experience on ITE products for Americas, Europe, Asia, and some Nebs understanding. Recently began a new opportunity, which encompasses EMC and Product Safety for automation. Only begun reading SEMI S2/S8, and IEC 61010-1.My

Re: [PSES] Testing a product with that uses a solar panel

But the point is the solar panel is integrated into the test sample and must be used as the power source. The only issue is what to use to illuminate the panel. It seems patently obvious to me that an ordinary incandescent bulb (of sufficient power) is the solution for EMI testing. Ken Javor

The panel in and of itself will not cause emission but the charging current profile sure can . Thanks! Charles Grasso W: 303-706-5467 From: DEREK WALTON [mailto:00734758d943-dmarc-requ...@listserv.ieee.org] Sent: Thursday, February 14, 2019 8:29 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject:

Re: [PSES] New EU enforcement regulations touches on all? product regulations/directives.

I've had a couple of inquiries recently from potential customers who have said "we want to sell this on Amazon but they are asking for an EMC report?" so maybe Amazon are (finally) starting to ask the right questions. I've seen non-EMC-compliant but CE marked power supplies sourced from Amazon
