The Progressive Dynamics PD4500 is a larger 50A RV power centre with split-leg AC distribution, an eighteen-position DC fuse panel and a removable converter module. The original factory wiring illustration locates its AC breaker banks, battery connections, disconnect terminals and converter outputs.

What the diagram labels identify
The listed components describe the connections and accessible parts in the original manufacturer drawing, rather than standalone replacement-part numbers.

| AC hot 1 / hot 2 | Separate black and red incoming AC supply legs |
| AC neutral | White incoming neutral conductor |
| AC ground | Incoming chassis/equipment ground |
| Converter AC supply | Separate 120V branch hot, neutral and ground |
| AC distribution banks | Circuit breaker positions for RV AC branch loads |
| DC fused outputs | Up to 18 fused branch positions |
| Blown fuse LED indicators | Optional individual branch diagnostics |
| Battery positive lug | Battery POS/BLK connection |
| Battery negative lug | Battery GND/WHT connection |
| DC disconnect lug | Position for an external battery-disconnect arrangement |
| Converter positive output | Positive connection from converter to DC fuse board |
| Converter negative output | Converter return connection |
| Output mode selector | Optional lead-acid/lithium charging mode switch |
| Charge Wizard indicator | Manual button and status light in the illustrated control area |
Match the exact power-centre model
The AC distribution panel is rated for a 120/240V 50A RV feed; the converter module itself is fed by a 105–130V AC branch circuit, not by applying 240V directly to the converter. The 12V converter section is available in 60A, 75A and 90A outputs. The panel provides up to 18 DC fused positions with higher-current positions designated by the manufacturer.
| Original model | DC output | Assembly | Details |
|---|---|---|---|
| PD4560AV | 60A | Complete power centre | 50A AC distribution, 60A DC converter |
| PD4575AV | 75A | Complete power centre | 50A AC distribution, 75A DC converter |
| PD4590AV | 90A | Complete power centre | 50A AC distribution, 90A DC converter |
| PD4560CSV | 60A | Replacement converter section | For documented PD4560-series power centres |
| PD4575CSV | 75A | Replacement converter section | Manufacturer-listed service section; not currently linked |
| PD4590CSV | 90A | Replacement converter section | For documented PD4590-series power centres |
Match the actual power centre to its converter-section rating. Progressive Dynamics identifies PD4560CSV for the 60A family, PD4575CSV for the 75A family and PD4590CSV for the 90A family. The 75A replacement remains unlinked because a matching current NewRVParts listing was not found. The PD4500 may mount vertically with its converter below or horizontally with the converter to the right, unlike the PD4000.

Compare these catalog photos with the full manufacturer model number on your installed unit. A complete power centre and a replacement converter section are different products, even when they share an output rating.
