The operating/instruction manual is part of the safety submittal/approval process and shall have correct ratings per the Type Test conditions. But sales-infected spec sheets on websites or on advertising brochures are not worthy of notice. Common problem in power industry.
If label and manual have different ratings - then the supplier's compliance guy should be directly interrogated.

Typically the voltage rating would be marked on the nameplate of the product, but some agencies will go look in the often embellished specifications in the operator manual for the voltage range. Some auto-ranging power supplies mark the a.c. input as a list of nominal voltages, as in "100/120/220/240V". ____________________________________________________________________________ ___ Ralph McDiarmid | Schneider Electric | Solar Business | CANADA | Regulatory Compliance Engineering From: Brian Oconnell <oconne...@tamuracorp.com> To: EMC-PSTC@LISTSERV.IEEE.ORG, Date: 12/03/2012 08:55 AM Subject: Re: [PSES] IEC 60601-1-2 autoranging supplies Rated by test certificate and CB report, or by the sales dept-infected spec sheet? That is, what is the rating on the unit's label? You can configure most variacs to provide well above the input voltage, but this may do strange stuff to the source impendence. Use a really really really big variac, or use an electronic source (Ametek, Chroma, etc).

We typically test at 90 Vac and 240 Vac. Many supplies I see now are rated up to 264 Vac though. Is anyone testing at 264V? Are there variacs out there to bump the input voltage, since our generator can't go much above 240?
