Rv power converter 30 amp3/10/2023 Typically, a battery may be subject to excess fluid loss during high ambient temperatures. Temperature-compensated charging will improve performance, whether the battery is a flooded lead-acid type, AGM or gel cell. Parallax’s TC series utilizes unique temperature-compensation technology. Ambient temperatures affect the way batteries charge or discharge and, of course, that leads to longevity expectations. Living in areas of extreme ambient temperatures presents challenges, even for the best batteries. With this latter feature, the electronic circuit uses 120-volt AC input current much more efficiently, producing up to 90 amps of DC output yet drawing only the current required to run a 65-amp converter. Parallax offers a 90-amp converter/charger (model 5490TC) with temperature compensation and a proprietary Power Factor correction. Several companies offer 80- and 90-amp converter/chargers to meet the highest demands of today’s advanced systems. RV electrical systems have more power demands than ever. Replacing an old single-stage converter with a multistage model may seem complicated, but it is well worth the time and expense, especially considering the former never properly conditions batteries. For instance, an 80 percent recharge can occur in two to three hours, instead of the roughly 24-hour charge rate of a single-stage converter/charger. The benefits are faster charging rates and cleaner DC voltage output. There are thousands of these converters in use.Įlectrical systems have advanced with the use of printed circuit boards and sensitive electronic equipment, creating the need for a more comprehensive charging system. For many years, the only available converters had a simple single-stage or fixed voltage design with an output of approximately 13.2 volts DC. Multistage converter/chargers with an equalization process are an effective method of charging lead-acid or other types of batteries. Parallax Power Supply’s converter/charger utilizes a unique temperature- compensation feature designed to maximize output in extreme temperatures. Here’s an encapsulation of what’s out there. Today’s converters have different amperage output ratings, depending on the RV’s 12-volt DC system requirement, and the ratings usually range from 45 to 90 amps in single and multistage configurations that may include an equalization mode designed to help batteries live a maximum life. This condition is the leading cause of battery failure. Proper charging will help prevent sulfation, a deposit of lead sulfate on the plates that adversely affects the ability of the battery to accept a charge. The rising cost of lead and advancements in technology have catapulted the price of batteries significantly during the past 20 years. In fact, many supply only a float charge, which in time will prevent the batteries from reaching maximum capability, from both power supply and longevity standpoints. While the concept is good, reality suggests that many of these basic single-stage converters do not condition batteries properly. They also are supposed to keep the batteries at least partially charged. As their name implies, they convert 120-volt AC power into 12-volt DC power for running multiple 12-volt DC appliances and accessories without draining the batteries. Modern electronic converters are quiet and efficient, operating automatically when the RV is plugged in to shorepower or when the generator is running.Ĭonverters have two basic jobs to perform. Compact size and a high degree of reliability enable manufacturers to install converters in convenient and inconspicuous places. In fact, some owners may not even know where the converter is located in their RV. Power converters fall into the category of “out of sight, out of mind” - literally. Converters are designed to provide 12-volt DC current and charge batteries - but not all are created equal
