<h3>About Magnum-Dimensions</h3><p>Magnum-Dimensions has established itself as one of the most respected names in mobile and stationary power conversion. Born from a legacy of innovation rooted in the Pacific Northwest, <strong>Magnum-Dimensions</strong> grew out of decades of inverter engineering expertise and has since expanded into a comprehensive portfolio of DC-to-AC power solutions trusted by professionals across a wide range of demanding industries.</p><p>The brand operates under the umbrella of Sensata Technologies, which united the Magnum Energy and Dimensions Inverter product lines into a single, cohesive brand. Today, Magnum-Dimensions products are manufactured in Everett, Washington and St. Paul, Minnesota, with UL and Intertek-certified production underpinning the quality assurance that field technicians, fleet managers, and off-grid enthusiasts have come to rely on.</p><h3>What Magnum-Dimensions Makes</h3><p>At the heart of the Magnum-Dimensions catalog are its industry-leading <a href="/11270-magnum-power-inverter-14297">power inverters</a>. These units convert DC battery power into clean, usable AC electricity, allowing users to run air compressors, drills, air conditioners, microwaves, computers, and virtually any AC-rated equipment wherever a proper DC power source is available. The lineup spans both pure sine wave and modified sine wave designs, with output ratings ranging from 300 watts all the way up to 12,000 watts in single and three-phase topologies, and DC input compatibility from 12 to 300 volts. Whether you&apos;re outfitting a recreational vehicle, a marine vessel, a utility truck, or a remote off-grid installation, there&apos;s a Magnum-Dimensions inverter engineered for the job.</p><p>Complementing the inverter lineup is Magnum-Dimensions&apos; advanced <a href="/11270-magnum-battery-charger-14307">battery charger</a> technology. Many of the brand&apos;s inverter/charger combo units feature power factor correction techniques — an innovative approach that improves charging efficiency across both sine wave and modified sine wave platforms. These integrated charger systems support a wide variety of battery chemistries, including Flooded, Gel, AGM, and Lithium Iron Phosphate (LFP), making them highly adaptable to modern energy storage setups.</p><h3>Key Product Series</h3><ul><li><strong>MS Series:</strong> A flagship pure sine wave inverter/charger line purpose-built for demanding mobile, backup, and off-grid applications, available in 12V, 24V, and 48V configurations.</li><li><strong>MMS Series:</strong> An economical pure sine inverter/charger solution for smaller mobile power needs, known for its lightweight, versatile design.</li><li><strong>MS-PAE Series:</strong> Magnum-Dimensions&apos; most robust renewable-energy-focused inverter/charger, with outputs reaching up to 17,600 watts.</li><li><strong>MSH Series:</strong> A hybrid inverter/charger that adds &quot;Load Support&quot; functionality, allowing incoming AC to synchronize with the inverter output for seamless power blending.</li><li><strong>MMP &amp; MP Panel Systems:</strong> Pre-wired panel solutions that simplify installation and system integration for both residential and mobile setups.</li></ul><h3>Industries Served</h3><p>Magnum-Dimensions products are widely deployed across recreational vehicles, marine applications, corporate and utility fleets, telecommunications, military operations, and renewable energy systems.

Product Details

The Magnum Energy CSWTS15 is a 15 Amp Transfer Switch designed for use in RV, marine, and off-grid power applications. This compact transfer switch automatically or manually switches between two power sources — such as shore power and an inverter — ensuring a seamless and safe transition without backfeeding or power interruptions.

Key Features:

  • 15 Amp rating — suitable for standard 120V AC branch circuits
  • Designed to work with Magnum Energy inverter/charger systems
  • Prevents backfeed between power sources for safe operation
  • Compact, durable construction for reliable long-term use
  • Ideal for RV, marine, cabin, and off-grid installations

The CSWTS15 is a purpose-built transfer switch that integrates cleanly with Magnum Energy's line of inverters and chargers. It provides a reliable switching solution for installations where a dedicated 15-amp circuit must be managed between alternate power sources, making it an essential component for any well-designed off-grid or backup power system.
