A. The input ranges shown on power supplies (nameplates) are the figures used when applications for safety standards are submitted so approval of the safety standards is already granted at the time of use within these ranges.
Furthermore, the specifications shown on documents such as catalogs are the input ranges of the operational assurance that we offer. Therefore, assurance for use within the specifications is given for use exceeding the ranges shown on the power supplies (nameplates) although the safety standards are excluded.
