Since your Progressive Dynamics converter has a dual fan setup the correct replacement would be the Lithium Converter Section part # PD4575LICSV.

Pd4575k18L has the dual fan setup came with normal marine/rv battery. What’s the difference in the Rv converter if you have just a regular battery in your camper do you need to replace with the lithium converter or can you just replace with regular converter

@EthanM Lithium batteries charge a higher voltage than standard batteries which is why they require a different setup entirely.

@Ethan You didn't mention what battery type you have but the part # PD4575K18LS8 is compatible with both lithium and lead acid batteries.
