Product Features
The Landworld LWD300-540S24-N is a naturally cooled 300W EV DC/DC converter designed to convert high-voltage battery power into a stable 24VDC supply for low-power vehicle electronics, monitoring-related loads and auxiliary systems. The converter supports a wide 200–800VDC input range and provides a nominal output current of 12.5A. Its rated output power is 300W, with a specified peak output of 360W. An IP67-rated enclosure and natural cooling design make the unit suitable for vehicle projects that require a sealed DC/DC solution without a cooling fan or liquid-cooling circuit. CAN-BUS communication, CAN and KL15 wake-up methods, low standby current and multiple electrical protection functions support integration into passenger EVs, commercial electric vehicles and electrified construction machinery. |
IP67 Enclosure Protection The Landworld 300W DC/DC Converter is IP67 rated, providing full protection against dust and water, ensuring reliable performance in harsh conditions. |
24-Hour Monitoring and Low Power Consumption Supporting 24-hour monitoring with low power consumption in sleep mode, the converter ensures continuous operation and energy efficiency for various applications. |

1. What are the main benefits of using the Landworld natural cooling 300W DC/DC Converter in compact systems?
The Landworld natural cooling 300W DC/DC Converter is ideal for compact systems due to its passive cooling design, which eliminates the need for additional cooling components. This results in a lighter and more cost-effective solution, making it suitable for applications like battery management systems and small electric devices.
2. How does the natural cooling system affect the converter's performance under varying load conditions?
The Landworld natural cooling 300W DC/DC Converter ensures stable performance across a range of load conditions. It effectively dissipates heat generated during operation, maintaining efficiency and preventing overheating, which is crucial for manufacturers aiming for reliable performance in diverse applications.
3. What is the expected lifespan of the natural cooling 300W Converter, and how can it be maximized?
The Landworld natural cooling 300W DC/DC Converter is designed for longevity, with an expected lifespan of over 8 years under normal operating conditions. To maximize its lifespan, manufacturers should ensure proper installation, avoid exposing the converter to extreme environmental conditions, and perform regular inspections to maintain optimal performance.
4. What is the main difference between this product and the modular 300W converter?
The LWD300-540S24-N uses a naturally cooled IP67 enclosure. The modular version is designed for integration into a larger customer-defined power system or enclosure. The appropriate configuration depends on the required protection level, packaging arrangement and thermal design.
5. Can the converter continuously provide 300W?
The nominal output power is specified as 300W, while the peak output power is 360W. Continuous operation still depends on input voltage, enclosure temperature, mounting conditions and thermal performance. Project-specific operating conditions should be confirmed during technical evaluation.
6. Does the converter support 24-hour operation?
The product is positioned for monitoring-related applications and includes low standby current, CAN communication and wake-up support. Whether a complete system can operate continuously depends on the total connected load, duty cycle, thermal conditions and vehicle power-management strategy.
7. Does the product provide a regulated 24V output?
The nominal output is 24VDC with a specified voltage accuracy of ±0.5VDC. The page also describes the output as adjustable. The permitted adjustment range and control method should be confirmed before integration.
8.Does the converter support CAN wake-up?
Yes. The available specification lists CAN and KL15 as wake-up methods and identifies CAN-BUS as the communication interface. The required protocol and message definitions should be provided during project matching.
9.Is full output power available across the complete 200–800VDC range?
The available specification confirms a 200–800VDC input range but does not provide a derating curve. Customers requiring full output at the minimum or maximum input voltage should confirm this condition with Landworld during technical evaluation.
10. What information is required for a quotation?
Provide the battery voltage range, required 24V load, continuous and peak power, CAN requirements, standby strategy, installation layout, cooling conditions, environmental standards, connector requirements, project schedule and estimated order volume.
