![]() Let’s say you're plugged in and you're using a couple of 12 volt overhead lights (2 amps) and a ceiling fan (4 amps). When your RV converter is working at its maximum capacity, which in this case is producing 45 amps for 12 volt appliances and accessories, it is drawing a full 8 amps out of the 30 amps available from the campground electrical supply. In other words a 45 amp converter is capable of running 45 amps worth of 12 volt appliances in the RV. Your RV converter is rated for a certain amperage i.e. It will use a small amount for items like the LP gas leak detector, clocks or maybe an aisle light, but not enough to really affect the amperage you are plugged into. You’re using available amps from the 30 amp electrical supply for whatever 120 volt appliances are running, but the converter is drawing almost 0 amps because you’re not using any DC accessories. Let’s say you plug your RV into a 30 amp electrical supply and you only use 120 volt appliances. Are you more confused now than when we started? Let’s try wording this a little different. When you’re plugged into an electrical source and you use DC appliances and accessories like fans, lights, pumps or the TV antenna booster you are drawing amps from the converter. When you plug your RV into an electrical source and use 120 volt appliances like the roof air conditioner, the microwave and a TV you are drawing amps from the available supply at the campground, usually 30 or 50 depending on your RV electrical system and the electrical supply you are plugged into. The AC amps we are using and the DC amps we are using. There are two types of amperage draw concerning your RV. The converter basically prevents your RV battery(s) from draining when you’re plugged in. If you weren’t plugged into an electrical source your RV battery(s) would supply the power to all of the 12 volt appliances and accessories in the RV. When you plug your RV into an electrical source, or when you use the onboard generator, the converters job is to reduce 120 volts AC down to 12 volt DC to supply power to all of the 12 volt appliances and accessories in the RV. Since, I believe, the converter is operating any time you plug into a 120 volt AC system (30 Amp), does this mean that in reality you only have 22 amps to work with (30 minus 8 = 22, and not considering clock draws, etc.)? I am developing an electric amp chart to hang inside a cabinet and I need to resolve this question as this would make a significant difference.įirst of all let’s talk briefly about what your RV converter does. Reader’s question: In one of your previous articles you list the RV converter as drawing 8 amps. I received one of these good questions the other day and thought there would be many other RVers who would like to hear the answer. Just when I thought we thoroughly covered the topic I get another good question about RV electrical systems that I failed to discuss in the previous articles. I received so many questions and comments from readers that the next month’s article was a follow up with additional information on RV electrical systems. Capable of charging your RV battery while also supplying power for your DC electronics.Some time ago I wrote an article about basic RV electricity. Easy Installation & Wide Application: With no need to re-wire, installation is only 10 minutes! RV inverter converter charger will fully charge and maintain any battery type while providing very clean DC power.Reverse battery protection avoids damage from improper battery lead connection. Such as Reverse Polarity / Short Circuit / Over Temperature / Over Load Protection. Fully Security Protections: RV smart converter applies multiple security protections to ensure the converter charger is fully protected during use.Operate the charger in well-ventilated areas only. Quiet operation is ensured as the cooling fan only runs when required by the electric load. High-Speed Cooling Fan: Variable speed intelligent cooling fan automatically monitors RV battery charger converter temperature and activates fan at speed required. ![]() 3-stage charging system built-in handles every charging need for the RV while dramatically extending the battery's life for long last usage.
