This high-performance converter ensures consistent voltage regulation, maintaining output within 1% under various load and line conditions, which is critical for sensitive electronic devices. Its robust construction features a powder-coated aluminum heat sink case with large fins that maximize air contact, effectively dissipating heat generated by the semi-conductors for cool operation and long-term durability. The PC boards are conformally coated to resist corrosion, and the heavy-duty shock mounts provide resilience in harsh environments, making this converter suitable for demanding applications such as vehicles or remote installations.\u003c\/p\u003e \u003cp\u003eEquipped with comprehensive protection circuits, the Newmar 32-12-50 includes current limiting, automatic thermal shutdown, short circuit proofing, reverse polarity protection, and overvoltage safeguards. These features enhance reliability and safety during operation, ensuring continuous performance even under adverse conditions. The converter's specifications include an output of 13.6 VDC, with an adjustable range from 12.6 to 14.5 VDC, capable of delivering up to 50 amps intermittently and 40 amps continuously, making it suitable for a variety of power needs. Its efficient switching at 40 kHz results in an 85% typical efficiency, minimizing energy waste and heat.\u003c\/p\u003e \u003cp\u003eDesigned for versatile use, the converter supports operation in temperatures from 0°C to 50°C, with linear derating at higher temperatures to prevent overheating. The unit features a compact size with a front panel terminal block, heavy-duty mounting flange, and conforms to safety standards with a 250 VDC isolation between input\/output and chassis. Optional accessories include an extreme vibration mounting kit, which enhances durability in high-vibration environments like mobile or off-road applications. The converter is suitable for use as a battery charger or in parallel redundant configurations when derated to continuous duty, providing flexibility for complex systems. Overall, the Newmar Power 32-12-50 DC Converter offers a durable, efficient, and protected power solution for demanding industrial and vehicular applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eExcellent regulation: Maintains output voltage within 1% under all line and load conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEffective heat dissipation: Large heat sink fins maximize air contact for cool operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCorrosion resistance: Conformal coating on PC boards and anodized aluminum case\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRobust protection circuits: Includes 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% switching efficiency at 40 kHz\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVersatile operation: Supports battery charging and parallel redundancy (derate required)\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTemperature resilience: Operates effectively from 0°C to 50°C with linear derating at higher temperatures\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable construction: Powder-coated housing, heavy-duty mounting flange, shock mounts for hostile environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIsolation: 250 VDC between input\/output and chassis for safety\u003c\/li\u003e\u003c\/ul\u003e","brand":"Newmar Power","offers":[{"title":"Default Title","offer_id":44441186402346,"sku":"102306","price":1060.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/102306XL.jpg?v=1780937576","url":"https:\/\/atticusgoods.com\/products\/newmar-power-32-12-50-dc-converter-for-negative-ground-systems","provider":"Atticus Goods","version":"1.0","type":"link"}
