<h3>About Parallax Power Supply</h3><p>When it comes to keeping your RV powered up and ready for the open road, few names carry as much weight as <strong>Parallax Power Supply</strong>. With roots stretching back to the early 1970s, Parallax has spent more than five decades refining and pioneering the electrical systems that RV owners depend on every day. Their converter/charger technology was among the first in the industry to adopt multi-stage charging, and that commitment to engineering excellence has never wavered.</p><p><a href="/7486-parallax-power-supply-battery-charger-14307">Battery chargers and converter/charger systems</a> sit at the heart of the Parallax lineup. Their proprietary <strong>TempAssure&trade;</strong> technology intelligently manages charging rates based on battery temperature, helping extend battery life and prevent overcharging — a level of sophistication that sets Parallax apart from generic alternatives. Whether you need a deck-mount unit or a full power center, Parallax offers solutions sized from 30 amps to 75 amps and beyond to match virtually any RV electrical load.</p><p>For RVers who need to run AC appliances off their house batteries while off-grid, Parallax also produces a range of <a href="/7486-parallax-power-supply-inverters-202149">power inverters</a> designed to seamlessly convert DC battery power into usable AC electricity. Paired with a Parallax converter/charger, an inverter rounds out a complete, self-sufficient onboard power system.</p><p>Reliable power distribution is just as important as generation. Parallax manufactures <a href="/7486-parallax-power-supply-circuit-breaker-2504">circuit breakers</a> that are ETL-listed and certified by Intertek to meet OSHA safety standards — giving you confidence that your RV&apos;s electrical circuits are properly protected.
