Its robust design ensures consistent performance in demanding environments, making it suitable for marine, RV, and industrial applications. The converter features excellent regulation, maintaining output voltage within 1% across all line and load conditions, which guarantees stable power delivery to sensitive electronic systems. The internal components are protected by a polyurethane conformal coating and housed in a corrosion-resistant anodized aluminum case with heavy-duty shock mounts, ensuring durability and long-term operation even in harsh conditions. Its high-efficiency switching at 40 kHz minimizes heat generation, which is dissipated effectively by large heat sink fins, promoting cool operation and extending component life. The device incorporates numerous protection circuits, including current limiting, thermal shutdown, short circuit proofing, reverse polarity, and overvoltage protection, providing peace of mind during operation. Designed with versatility in mind, the converter supports intermittent and continuous duty cycles, with a maximum on time of 2 minutes for intermittent use and full 24-hour operation at continuous duty, making it adaptable to various power demands. Its compact case measures approximately 3.5 inches in height and width, with a depth of 1.75 inches, and weighs about 1 pound, making installation straightforward in tight spaces. Operating in temperatures from 0 to 50°C, the converter features thermal shutdown at 70°C and derates linearly at higher temperatures to ensure safe operation. The device's construction includes a powder-coated aluminum heat sink case, a front panel terminal block, and a heavy-duty mounting flange, facilitating secure installation. Optional features allow for battery charging or parallel redundant operation, enhancing system flexibility. The Newmar Power 24-12-3 is CE-marked, ensuring compliance with international safety standards, and is built to withstand challenging environments with its rugged construction and comprehensive protection features. Whether used in vehicle, marine, or industrial settings, this converter provides a dependable power conversion solution, backed by the manufacturer's direct support for any technical concerns.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eExcellent regulation maintains output within 1% under all line and load conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLarge heat sink fins optimize air contact for cool operation and component longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePolyurethane conformal coating and corrosion-resistant anodized aluminum case ensure durability in hostile environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNumerous protection circuits including current limiting, thermal shutdown, short circuit proof, reverse polarity, and overvoltage protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports intermittent and continuous duty cycles with flexible operation options\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompact design with approximately 3.5 inches in height and width, weighing about 1 pound\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOperating temperature range from 0° to 50°C with thermal shutdown at 70°C\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRugged construction featuring powder-coated aluminum case, front panel terminal block, and heavy-duty mounting flange\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInternally adjustable output voltage from approximately 12.6 to 14.5 VDC\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh efficiency of about 85% with switching frequency of 40 kHz\u003c\/li\u003e\u003c\/ul\u003e","brand":"Newmar Power","offers":[{"title":"Default Title","offer_id":44441197051946,"sku":"102300","price":167.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/102300XL.jpg?v=1780938057","url":"https:\/\/atticusgoods.com\/products\/newmar-power-24-12-3-dc-converter-for-negative-ground-systems","provider":"Atticus Goods","version":"1.0","type":"link"}
