Re: [PSES] Using an IEC60950 power supply to power an EN61010 equipment

Gary, One other concern you should be aware of. With 60950, the majority of products are evaluated to Overvoltage Category II, while it is possible that your 61010-1 product is evaluated to OV Cat III. This will have a significant effect on determination of your minimum  clearance requirements as well as your surge immunity levels when applying EN 61326-1 for your EMC evaluation. Your 60950-1 approved power supply may not be adequate to the task.  Best to double check.the data sheet and if necessary call the manufacturer. Also, I always like to get a full list of the conditions of use for the power supply.  Thanks -doug Douglas Powell http://www.linkedin.com/in/dougp01     Sent from my BlackBerry 10 smartphone on the Verizon Wireless 4G LTE network.

The Other Brian   EN 61010-1:2010 section 1.1.3 says, NOTE Computing devices and similar equipment within the scope of IEC 60950 and conforming to its requirements are considered to be suitable for use with equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in this standard (see 5.4.4 second paragraph).   Section 5.4.4 says, If equipment conforming to IEC 60950 is used with equipment conforming to this standard, and if there is a HAZARD due to moisture or liquids, the instructions for use shall specify any additional precautions necessary.   Also, read section 14 regarding the use of components and subassemblies “such as power supplies”…   From: Darnel, Gary [mailto:gary.dar...@thermofisher.com] Sent: Monday, September 23, 2013 5:01 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] Using an IEC60950 power supply to power an EN61010 equipment   Dear All,   I have a question about insulation requirements of the EN61010:2010 standards (clause 6).   Are the insulation requirements of EN61010 / IEC61010:2010 identical to those found in the latest IEC60950 (2009 I believe, including all amendments)?   Basically I need to know if I use a third party certified power supply marked to EN60950:2009, will it meet the insulation requirements of EN61010 (clearance, creepage, protective bonding…etc)   Maybe in a nutshell, I am wondering where the EN61010 insulation requirements were derived from.  Are they the same source as the EN60950 requiements.     Thanks,   Gary Darnel   - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
