Designed for reliable operation in demanding environments, this converter features excellent voltage regulation, maintaining output within 1% under all line and load conditions, ensuring consistent power delivery. Its robust construction includes a large heat sink with fins for optimal air cooling, which helps dissipate heat generated by semi-conductors, prolonging component life and ensuring cool operation during extended use.\u003c\/p\u003e\u003cp\u003eThe unit is built with durability in mind, featuring polyurethane conformal coating on PC boards and a corrosion-resistant anodized aluminum case with heavy-duty shock mounts. These features enable the converter to withstand harsh environments, including exposure to moisture and vibration. Safety is prioritized with various converter and load protection circuits, such as current limiting, thermal shutdown, short circuit proofing, reverse polarity protection, and overvoltage protection, all carrying a CE mark for compliance. This broad protection suite ensures the converter's resilience and safe operation in critical applications.\u003c\/p\u003e\u003cp\u003eMeasuring approximately 6 inches high, 4.7 inches wide, and 14 inches deep, the converter weighs about 7.5 pounds, making it suitable for a variety of installation scenarios. It delivers a continuous output of 20 amps and an intermittent peak of 25 amps at 13.6 VDC, with an adjustable voltage range from 12.6 to 14.5 VDC. The converter operates efficiently with an typical efficiency of 85% and a switching frequency of 40 kHz, providing reliable power with minimal ripple. Its isolation ratings of 250 VDC between output and chassis, and input and chassis, enhance safety and system integrity.\u003c\/p\u003e\u003cp\u003eDesigned for versatile use, the Newmar Power 32-12-25 can be mounted on vehicles with high-vibration environments using an optional extreme vibration mounting kit. This kit acts as a super shock absorber, protecting internal components from shock and vibration stresses. The converter is suitable for continuous operation, with a thermal shutdown feature activating at 70°C to prevent overheating. Operating temperatures range from 0°C to 50°C, with derating applied at higher temperatures to ensure reliability. The powder-coated aluminum case, front panel terminal block, and heavy-duty mounting flange make installation straightforward and durable. Overall, the Newmar Power 32-12-25 DC Converter offers a dependable, high-performance power solution tailored for demanding communication and navigation systems in challenging environments.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eExcellent Voltage Regulation: Maintains output within 1% under all line and load conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeat Management: Large heat sink fins for optimal air contact and cooling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRobust Construction: Polyurethane conformal coating and corrosion-resistant anodized aluminum case with shock mounts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComprehensive Protection: Current limiting, thermal shutdown, short circuit proof, reverse polarity, and overvoltage protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh Efficiency: Typical 85% efficiency with 40 kHz switching frequency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIsolation: 250 VDC isolation between input, output, and chassis\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable Output: Internally adjustable voltage from 12.6 to 14.5 VDC\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable Design: Powder-coated aluminum case and heavy-duty mounting flange\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVersatile Use: Suitable for continuous or intermittent operation with optional vibration mounting kit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eThermal Safety: Shutdown at 70°C to prevent overheating\u003c\/li\u003e\u003c\/ul\u003e","brand":"Newmar Power","offers":[{"title":"Default Title","offer_id":44441192398890,"sku":"102304","price":708.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/102304XL.jpg?v=1780937630","url":"https:\/\/atticusgoods.com\/products\/newmar-power-32-12-25-dc-converter-for-negative-ground-systems","provider":"Atticus Goods","version":"1.0","type":"link"}
