Converter 240W 33.6~67.2V-24V 10A DDR-240C-24

Universal DC/DC converter for DIN rail

The DDR-240C-24 from MEAN WELL is a reliable power source designed for demanding industrial applications, particularly in railway applications. The device converts an input voltage range of 33.6~67.2V DC to a stable output voltage of 24V DC with a power of 240W, delivering a current of up to 10A. Its compact dimensions (40 mm width) allow for easy mounting on DIN rail TS-35/7.5 or 15, saving valuable space in control cabinets.

Application and design features

The converter is designed for applications requiring high reliability and safety. It meets the stringent standards of EN50155 (on-board electronics for rail applications) and EN45545-2 (fire safety in rail vehicles), making it an ideal solution for power supply systems in trains, trams and other rail vehicles. A wide operating temperature range (-40°C to +70°C) allows it to be operated in harsh environmental conditions.

The converter design allows for parallel operation up to 960W (3+1), allowing you to increase the available power without the need for additional devices. The DC OK relay output signals correct operation of the converter, and the lack of required minimum load facilitates integration with various systems. Output voltage adjustment allows for precise adjustment of power supply parameters to the needs of a specific application. Additionally, the ability to momentarily overload at peak to 150% ensures stable operation even with sudden changes in load.

Safety and protection

The converter is equipped with a comprehensive set of protections, protecting both the unit itself and the devices connected to it: short-circuit, overload, overvoltage and reverse polarity protection. Input/Output isolation with a value of 4 kVdc provides additional safety and minimizes the risk of electromagnetic interference. Cooling is done by free air convection, which eliminates the need for additional fans and reduces the risk of failure related to their damage.
