Progressive Dynamics 4000 Series PD4045KV Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel

Simplify your RV's power systems with the Progressive Dynamics PD4045KV 4000 Series Mini RV Converter with Charge Wizard and AC/DC Distribution Panel. This 2-in-1 unit combines a 45-amp multifunction converter/charger with a complete AC/DC distribution panel — consolidating two components into one compact unit that fits where a full-size panel won't.

2-in-1 Design Saves Space and Install Time

What sets the PD4045KV apart from a basic converter is the integrated distribution panel — combining two components into a single unit:

• AC/DC distribution panel — provides power to AC and DC applications throughout your RV
• 45A multifunction converter/charger — uses shore power to quickly charge batteries while providing continuous power to your 12V loads

Fewer separate components, less wiring complexity, less wall space — perfect for smaller RVs, trailers, or installations where space is at a premium. Hardwired installation into your existing RV electrical system.

Lithium AND Lead-Acid Compatible

The PD4045KV is engineered to handle modern multi-chemistry battery setups:

• Lithium-ion (LiFePO4) — uses a custom high-voltage charging profile for full, quick charge
• Flooded Lead Acid — multistage charging
• AGM — multistage charging
• Gel — multistage charging

That means whether you're running lead-acid today or upgrading to lithium tomorrow, this converter handles both — no need to replace your converter when you upgrade your batteries.

Intelligent Charge Wizard Multistage Charging

For lead-acid batteries (FLA, AGM, gel), Progressive Dynamics' patented Charge Wizard technology automatically monitors battery voltage and begins charging when needed — running multistage charging that delivers faster recharge while extending battery life compared to older single-stage chargers. For lithium batteries, the unit uses a separate high-voltage output profile designed specifically for LiFePO4 chemistry.

Comprehensive Distribution

The integrated distribution panel includes:

• AC distribution: Up to 6 branch circuits rated at 30 amps (using tandem breakers)
• DC distribution: (2) 30-amp fuses and (10) 20-amp fuses

Please note: AC breakers and DC fuses are sold separately.

Drop-In Replacement for Many Brands

The PD4045KV is a direct cross-reference replacement for several common converter/charger units, making it a straightforward upgrade option if your existing unit has failed:

• WFCO: WF-8945ANP, WF-8740P
• Parallax: 7345, 8345, 7145
• Powermax: PPC-32, PPC-45

Built-in Safety Features

Multiple layers of protection safeguard the converter and your RV's electrical system, with heat-resistant polymer construction built for long-term durability in RV environments.

UL Listed & Made in USA

The PD4045KV is UL listed and proudly made in the USA — backed by a 2-year limited manufacturer warranty.

Considering Other Progressive Dynamics All-In-One Units?

We carry the full Progressive Dynamics all-in-one converter/panel range — pick by power needs and panel size:

• Progressive Dynamics PD4060KV (60A, 4000 Mini) — same compact panel form factor as this unit with more charging power, for mid-size RVs and trailers
• Progressive Dynamics PD4560AV (60A, 4500 Series) — same 60A converter capacity in a full-size 4500 Series panel (12 AC + 18 DC fuses)
• Progressive Dynamics PD4590AV (90A, 4500 Series) — largest capacity full-size panel for fifth wheels and toy haulers

Just Need the Converter Section?

If your PD4045KA Power Control Center has a failed converter section but the rest of the panel is fine, the Progressive Dynamics PD4045CSV Replacement Converter Section is the drop-in repair part — same 45A Charge Wizard converter with Lithium/Lead-Acid switch, designed to slide into your existing panel without rewiring the entire distribution box.
