Hello, I am "attempting" to design a low speed modem incorporating the Rockwell RC224ATF and the Midcom 671-8005 transformer. However I need to specify a surge/overvoltage protector eg Teccor Sidactor type. These "MOV" are working voltage dependent. For a modem complying to FCC Part 68, what is the working voltage? Is there an operating range?
Thank You, JOHN COYLE
