Converter 400W 67.2~154V-12V 33.4A DDR-480D-12

DC/DC Converter for Industrial and Railway Applications

The DDR-480D-12 converter from MEAN WELL is a robust and reliable power source designed for demanding industrial applications, including railway systems. The device is characterized by high efficiency and a wide input voltage range, making it a versatile solution for various installations. The use of advanced protection features guarantees safe and stable operation.

Construction and application

The DDR-480D-12 converter converts DC voltage from 67.2~154V to 12V DC, delivering an output power of up to 400W (33.4A). The design adapted for mounting on a TS-35/7.5 or 15 DIN rail facilitates integration with existing systems. Thanks to compliance with EN50155 and EN45545-2 standards, the converter is ideally suited for use in railway transport – from powering control systems to lighting and on-board equipment. Parallel operation allows the output power to be increased to 1920W (with a 3+1 connection), which is particularly useful in extended installations.

Key features and benefits
