|   Converters/Power 
                    Supply 
                    units are designed to convert 120 volts AC (household electrical 
                    energy) into nominal 12 volt DC (automotive electrical energy). 
                     A converter/power 
                    supply is used to run the pumps, motors, fans and lights in 
                    recreation vehicles. If working properly a converter/power 
                    supply will protect against low line voltage and spikes coming 
                    from the AC power source or from improperly adjusted generators. 
                     They 
                    should also minimize radio and TV equipment interference, 
                    especially on the lower frequency bands.  |
