Progressive Dynamics' Mighty Mini PD4000 power centres combine a 120V AC distribution section with fused 12V DC circuits and a front-accessible converter. The manufacturer's drawing identifies the battery positive and negative lugs, DC disconnect position, reverse-battery indicator and AC breaker compartment.
Original manufacturer wiring and fuse diagrams
Use the manufacturer's labelled illustration to locate the AC distribution compartment, converter and DC fuse-board connections. This is an electrical layout reference, not an exploded parts drawing.

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.
| Diagram component | Function and identification |
|---|---|
| AC main breaker | Main breaker and hold-down clip in AC compartment |
| AC hot input | Incoming 120V supply at the main breaker |
| AC neutral bus | Neutral connections for branch circuits |
| AC ground bar | Grounding termination and chassis bonding |
| Converter AC wires | Separate hot, neutral and ground leads for the converter |
| Converter DC positive | Black converter positive output terminal |
| Converter DC negative | White converter negative output terminal |
| Battery positive | House-battery POS/BLK lug |
| Battery negative | House-battery GND/WHT lug |
| DC disconnect jumper | Link or external DC disconnect connection shown in diagram |
| Reverse battery indicator | LED showing reverse battery fuse condition |
| DC fuse board | Twelve positions, rating depends on circuit and fuse location |
Match the exact power-centre model
The 4000-series panel supports a 30A AC main, up to seven AC branch circuits and twelve DC fuse holders (two up to 30A and ten up to 20A). The 45A model uses PD4045CSV for converter-section replacement; the 60A model uses PD4060CSV. A converter-section kit is not the complete enclosure, breaker panel or wiring harness.
| Original model | DC output | Assembly | Details |
|---|---|---|---|
| PD4045KV | 45A | Complete power centre | 45A converter assembly |
| PD4060KV | 60A | Complete power centre | 60A converter assembly |
| PD4045CSV | 45A | Replacement converter section | For documented PD4045 power centres |
| PD4060CSV | 60A | Replacement converter section | For documented PD4060 power centres |
The current PD4045KV and PD4060KV power centres include a battery-chemistry selection feature, but older PD4000 versions may differ. Verify the model label, converter-section number and charging requirements before choosing a replacement. The manufacturer specifies horizontal mounting with the converter section to the left.

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.
