Converter 480W 67.2~154V-24V 20A DDR-480D-24

DC/DC Converter – Reliable Power Supply for Demanding Applications

The DDR-480D-24 converter from MEAN WELL is a high-performance DC/DC converter designed for operation in harsh industrial conditions, particularly in railway applications. The device converts an input voltage range of 67.2~154V DC to a stable output voltage of 24V DC, delivering up to 480W of power. This is a robust solution for systems requiring a reliable power supply where resistance to interference and high efficiency are key.

Design and Application

The converter is designed for mounting on a standard DIN rail TS-35/7.5 or 15, making it easy to integrate with existing installations. Thanks to compliance with EN50155 (railway) and EN45545-2 (fire safety in railway vehicles) standards, it is an ideal choice for applications in rail transport – from powering control systems to lighting and on-board equipment. However, thanks to its wide input voltage range and high efficiency, the converter also finds applications in other industries, such as industrial automation, renewable energy, and security systems.

Key Features and Benefits

• Wide input voltage range (67.2~154V DC): Enables operation in different power systems without the need for additional converters.
• High efficiency (up to 92%): Minimizes energy losses and reduces operating costs.
• Compliance with railway standards (EN50155, EN45545-2): Guarantees safety and reliability in demanding railway applications.
• Convection cooling: Eliminates the need for fans, increasing reliability and reducing maintenance costs.
• Protections: Built-in protections against short circuit, overload and overvoltage protect both the converter and connected devices. It also has reverse polarity protection.
• Parallel operation capability: Allows increasing the output power by connecting multiple converters (up to 1920W in a 3+1 configuration).
• DC OK relay output: Enables remote monitoring of the power supply status.
• Output voltage adjustment: Allows precise adjustment of the voltage to the application requirements.
• Temporary overload to 150%: Provides power reserve for short load peaks – useful when starting motors or other devices with high inrush current.

DDR-480D-24 is not only an efficient power source, but also an investment in the reliability and safety of your systems. Its solid construction and advanced features make it the ideal choice for both professional installers and end-users looking for a proven solution for years to come.
