DC - DC High - reliability On - vehicle Step - down Power Supply Solution: 24V to 12V, 10A

With the increasing prevalence of onboard electronic devices in various commercial vehicles, construction machinery, special vehicles, and new energy logistics vehicles, the demand for stable and efficient power supplies is becoming increasingly urgent. Our company's products are specifically designed for harsh onboard environments.24V to 12V 10A 120W Non-isolated DC-DC ConverterWith its high reliability, wide input voltage range and comprehensive protection functions, it has become an ideal secondary power conversion solution for various automotive 12V electronic devices.

Core product advantages and compatibility with automotive applications

1. Excellent environmental adaptability, fearless of harsh vehicle operating conditions

   • Wide input voltage (18V-35V)It perfectly adapts to the large fluctuations in the 24V system battery voltage during vehicle start-up, acceleration, idling, and braking, ensuring a continuous and stable power supply.

   • IP67 protection rating & full potting processCompletely dustproof and waterproof, and effectively resists oil stains and salt spray corrosion, easily coping with water splashes on the chassis, high temperature and humidity in the engine compartment, and dusty outdoor environments.

   • Excellent vibration resistance and direct cooling designThe mechanical structure is robust and can withstand continuous vibration and impact during vehicle operation; the efficient heat dissipation design ensures stable operation for extended periods even in space-constrained and poorly ventilated installation locations within the vehicle.

2. High efficiency and high reliability ensure continuous system operation.

   • Up to 95% conversion efficiencyIt greatly reduces power loss and heat generation, lowers the overall vehicle heat load, and improves energy efficiency, which is especially beneficial to the driving range of new energy vehicles.

   • 100% aging test & up to 100,000 hours MTBFIt undergoes rigorous testing before leaving the factory, has a long mean time between failures (MTBF), and meets the stringent requirements of vehicle-mounted equipment for lifespan and reliability.

   • Comprehensive circuit protection mechanism：

     • Overcurrent, overtemperature, and short circuit protectionIt effectively prevents damage to the power supply itself caused by load equipment failure, wiring errors or overheating, thus avoiding potential electrical safety hazards in vehicles.

     • Low voltage protectionWhen the input voltage is too low (such as when the battery is severely depleted), the output is shut down in an orderly manner to protect the converter and alert the user to check the main power system.

3. Flexible installation and strong compatibility

   • Compact structure and easy installationIt is easy to integrate into the vehicle's control cabinet, equipment compartment, or directly installed near the equipment, simplifying wiring.

   • Non-isolated designWhile ensuring the system's common ground requirements, it provides a more efficient and economical solution suitable for most automotive electronic devices with non-safety isolation requirements.

Typical automotive application areas
