24V to 12V DC Voltage Converter — 12V 30A (360W) Key benefits Converts higher-voltage systems (15–40V) down to a stable 12V output at up to 30A (360W), so 12V devices run reliably on 24V or 18V vehicles and equipment. Protects sensitive 12V electronics from damaging over-voltage or fluctuations common in commercial vehicles, RVs and marine environments. Compact, rugged design with IP67 waterproof alloy housing and 12 cm wire leads makes installation simple even in exposed or tight locations. What it does and why you need it Efficient step-down DC converter that lets you use standard 12V devices (lights, radios, dash cams, fridges, pumps, navigation and other accessories) on 24V or 18V electrical systems without rewiring or replacing equipment. Eliminates the need for bulky resistors or unreliable dropper solutions by providing a stable, regulated 12V supply rated for continuous 30A load. Key features Input range: 15–40V DC — works reliably with 24V systems and also as an 18V to 12V converter. Output: 12V DC, 30A (360W) stable output for high-current 12V loads. Housing: IP67 waterproof alloy housing for protection against water and dust in outdoor and marine use. Form factor: Compact, lightweight unit with 12 cm wire leads for easy placement and wiring in tight spaces. Safety and reliability Built-in protections for over-voltage, under-voltage, overload, overheating, and short circuits to maintain stable operation and protect both the converter and connected devices. Heavy-duty construction suited to automotive, truck, van, and marine applications where vibration and exposure are common. Practical use scenarios Truck fleet: Power dash cameras, cabin lights and in-cab chargers from the vehicle’s 24V system without modifying devices. Campervan/RV conversion: Run 12V refrigerators, LED lighting and stereo equipment from a 24V alternator or battery bank. Marine and boating: Supply 12V electronics such as navigation units, bilge pumps and instruments from higher-voltage onboard systems with an IP67-rated enclosure. Installation notes Connect using the provided 12 cm wire leads; secure mounting in a dry, ventilated area when possible. Observe polarity and recommended wiring practice to ensure safe operation. Designed for inline installation as a dropper/step-down converter; no additional cooling accessories are typically required for normal use within rated loads. Technical summary Input: 15–40V DC Output: 12V DC, 30A (360W) Housing: IP67 waterproof alloy Leads: 12 cm wire leads Protections: over-voltage, under-voltage, overload, overheating, short circuit This heavy-duty DC converter provides a compact, reliable and protected way to power 12V equipment from 24V or 18V electrical systems in automotive, commercial and marine settings.
