Message-ID: <4459@iitmax.IIT.EDU> Date: 4 Nov 90 20:29:51 GMT Reply-To: thssdwv@iitmax.iit.edu (David William Vrona) Organization: Illinois Institute of Technology Lines: 1 I heard recently that it is not a good idea to plug a transformer, like those used on modems, calculators, and the like, into a UPS. Something about the UPS not having a true sine wave ??? Is this true? What's the scoop?
