Thanks for the picture! I checked with Progressive Dynamics the replacement power converter you need for your Parallax Series 7300 Model 7345 is the Replacement Converter for Parallax/Magnetek or WFCO RV Power Centers - 45 Amp item # PD4645V.

@BrandonM The closest we have to a 30 amp converter is the 35 Amp Replacement Section for AC/DC Power Distribution Panel item # PD4635V.

Jarred, Is the PD4645V just the bottom part of the 7300 7345 pictured? In other words do you use the existing breakers and fuse panel and just replace the converter/charger part. Thank you! Fred

@FredB Yes, that is correct. The Progressive Dynamics Replacement Section for AC/DC Power Distribution Panel item # PD4645V is just the bottom portion of the picture. You'll keep everything else in the power center.

My setup is exactly the same. But I need the circuit board one the bottom. My coil burnt out, and one of the other round circuits seemed to have popped on the top. Does this replacement come with that circuit board?

@JerredH so once I receive it, all, I have to do is pull the whole unit out and install the whole new unit, correct? And if I receive it and it isn't what I need, is it returnable?And fully refundable?

@Philip Yes, that is correct. Yes, it is returnable and refundable if it's not what you need. But you'll be good because the item # PD4645V is the replacement for your series 4300 model 4345.
