I run my pcs on a double conversion true sine wave UPS. It is designed to run continuously. It converts to DC, which is easy to filter, then creates a voltage and frequency regulated sine wave.
Modified sine is just a square wave. Complete junk. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
