Magnatek 7455 not working

Progressive Dynamics makes a replacement for the old Magnateks that are way more superior.

I,ve made the change you need, same one in my rv went bad, get one from progressive ,took about 2 hrs for a easy change over, and if you get stuck they,ll help you out over the phone.

I changed out to a IOTA 45amp been working great for the last three years, trouble free.

Which converter is best the Progressive PD 9620C

Or the Iota DLS-55

Can I safely install the 60 amp where I currently have a 55amp.

wbrowning,
I've sent you a couple of PM's. I may have something for you.

I just read them I'm thinking of going with the PD9260C because it will DE sulfate the batteries.
