All, IEC 60601-1-2 requires surge, burst, and dropouts be done at the maximum and minimum rated voltages for autoranging supplies. 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? Thanks, David
