What is the primary function of a power converter in a recreational vehicle?

The primary function of a power converter in a recreational vehicle is to convert 120V AC power to 12V DC power. This is crucial because most of the systems and appliances in an RV, such as lighting, water pumps, and control systems, operate on 12V DC power. When an RV is connected to an external power source, such as a campground electrical system, the power converter takes the incoming 120V AC and steps it down to the necessary 12V DC to power these components efficiently.

Using a power converter ensures that all the DC-powered devices operate correctly and safely, maintaining the energy needs of the RV while on shore power. This conversion is essential for the daily use of RV amenities when not relying solely on batteries.
