The Centurion CS 2000 (often listed as the CS2000 or CS 2000 XL) is a classic power converter found in many vintage RVs, pop-up campers, and travel trailers. Manufactured by Centurion 3000 (a brand later associated with Pacific Century and Parallax), this unit manages your RV's electrical ecosystem. It converts 120V Alternating Current (AC) shore power into 12V Direct Current (DC) power to run lights, fans, and pumps, while also passing AC power to your wall outlets.
The wiring for the CS 2000 typically involves five primary connections across the AC input and DC output sides. AC Input (Shore Power/Generator): Black Wire: Connects to the AC "hot" source (shore power or generator). White Wire: Connects to the AC neutral source. Green Wire: Connects to the metal ground point on the RV. DC Output (Battery/12V Systems):
Secure the Centurion CS 2000 housing into its designated cutout cabinet. Ensure there is at least a few inches of clearance behind and around the unit for ventilation, as these older linear converters generate significant heat. Step 3: Wire the 120V AC Side
Connect the wire to the screw terminal on the Main circuit breaker.
If your 120V microwave and outlets work, but your 12V lights are dead while plugged into shore power, the converter section may be failing. centurion cs 2000 power converter manual wiring diagram
When plugged into 120V AC shore power, the converter transforms that electricity into 12V DC power to run your lights, water pump, and exhaust fans. It also features standard AC circuit breaker slots to distribute 120V power to your camper's wall outlets and refrigerator.
The internal relay closes, allowing 12V DC power to flow backward from the battery (via the red wire) into the fuse panel.
All incoming and outgoing AC neutral wires connect to this insulated metal strip.
The Centurion CS 2000 power converter may be a relic of RV electrical systems past, but with careful research and a methodical approach, it can still be understood, serviced, and replaced. By using the practical wiring insights and troubleshooting steps shared by the RV community, you can keep your rig's electrical system running safely. For a long-term, hassle-free solution, upgrading to a modern power converter is a worthwhile investment in your RV's reliability and your own peace of mind. The Centurion CS 2000 (often listed as the
In RV DC systems, white is typically the "ground" or negative return. These connect to the large negative terminal on the back of the unit. Battery Connection:
Due to its age, the CS2000 is no longer in production and is widely considered an unreliable power converter by today's standards. If you are experiencing repeated failures or would like to modernize your RV's electrical system, replacement is the recommended path.

Before opening the converter casing, unplug the shore power cord and completely disconnect the negative cable from your RV battery.
The wiring diagram is not merely a suggestion; it is the schematic blueprint of the unit’s nervous system. For the technician or DIY enthusiast, the diagram is essential because the CS 2000 acts as a bridge between two distinct electrical worlds: the 120-volt shore power coming from the grid and the 12-volt system of the RV. Misinterpreting the connections between these two systems can result in catastrophic damage to the unit, the RV’s appliances, or personal injury through electric shock. Therefore, the diagram serves as the primary document for risk mitigation during installation and repair.
