Product Features
The Landworld LWD6K-540S27-M is a compact 6kW modular EV DC/DC converter designed to convert high-voltage traction battery power into a stable 27.5VDC supply for 24V vehicle auxiliary electrical systems. It supports a 400–750VDC input range, provides a nominal output current of 218A and achieves an efficiency of at least 95% under specified nominal-voltage conditions. With dimensions of 242 × 132 × 53mm and a weight of no more than 2.5kg, the module is suitable for electric commercial buses, heavy-duty electric vehicles and other vehicle platforms that require high low-voltage output power within limited installation space. As a modular product, the converter is intended to be integrated into a customer-designed enclosure and thermal-management system. The completed system must provide the required cooling, environmental protection, mounting structure, electrical interfaces and vehicle-level validation. |

1. How can I verify the specifications of the Landworld 6kW DC/DC Converter?
o verify the specifications of the Landworld 6kW DC/DC Converter, you can refer to the official product datasheet available on the Landworld website. Additionally, you can contact our customer support team for detailed information regarding power ratings, efficiency, and other technical parameters to ensure it meets your application needs.
2. What safety features are included in the Landworld 6kW DC/DC Converter?
The Landworld 6kW DC/DC Converter includes multiple safety features such as redundant protection mechanisms to ensure reliable operation in various environments. These features help prevent damage from overloads, short circuits, and overheating, providing peace of mind for users in critical applications.
3. Can the converter be used in harsh environments?
Yes, robust construction and advanced thermal management of the Landworld 6kW DC/DC ensure reliable performance in high-stress conditions, making it suitable for applications in electric construction machinery and other challenging settings.
4. Can the converter continuously provide 6kW?
The nominal output rating is 6kW under approved operating conditions. Continuous output capability depends on input voltage, module temperature, thermal-interface performance and the customer cooling system.
5. Can multiple modules be connected in parallel?
Parallel operation should not be assumed from the modular structure alone. Current sharing, synchronization, master-slave control and fault isolation require a specifically approved parallel solution.
6. Does the converter support CAN communication?
Yes. The converter supports CAN-BUS communication and CAN/KL15 wake-up. The CAN protocol, message identifiers and diagnostic functions must be confirmed for each vehicle program.
7. Is the converter suitable for electric commercial buses?
It can be evaluated for electric commercial buses using a compatible 400–750VDC traction battery and a 24V auxiliary network. Final suitability depends on the vehicle load profile, thermal design, enclosure protection and validation requirements.
8. Does the converter support remote software updates?
The converter supports software upgrade and fault-diagnosis functions. Remote or over-the-air updating should only be claimed when the complete vehicle system includes an approved remote-update architecture.
