Converter 480W 33.6~67.2V-24V 20A DDR-480C-24

DC/DC Converter for Industrial and Railway Applications

The DDR-480C-24 converter from MEAN WELL is a reliable power source designed to operate in demanding industrial conditions, including railway applications. The device converts DC input voltage (33.6~67.2V) to a stable 24V output voltage, delivering up to 480W of power. Thanks to compliance with EN50155 and EN45545-2 standards, the converter meets the stringent safety and reliability requirements of railway transport.

Design and Functionality

The converter is characterized by a robust design, allowing for mounting on a standard DIN TS-35/7.5 or 15 rail. It provides high efficiency (up to 92% depending on the model), minimizing energy losses and heat generation. Additionally, it has built-in protection against short circuit, overload and overvoltage, protecting both the converter itself and the devices connected to it. It is worth noting that the device does not require a minimum load, which increases its flexibility in various applications. The DC OK relay output indicates correct power operation.

Applications and Benefits

The DDR-480C-24 converter is an ideal solution for a wide range of applications, such as:

• Uninterruptible Power Supply (UPS) systems: Provides stable power to critical devices in the event of a mains power failure.
• Railway applications: Meets the safety standards required in railway transport – traffic control systems, lighting, passenger information systems, etc.
• Industrial automation systems: Powering PLC controllers, sensors and other automation devices.
• Monitoring and CCTV systems: Stable power supply for industrial cameras and recorders.
• Renewable energy: Used in photovoltaic and wind systems as an energy conversion element.

Thanks to the possibility of parallel operation (up to 1920W with a 3+1 connection), the output power of the system can be easily increased to suit individual needs. Output voltage adjustment allows for precise adjustment of power parameters to the requirements of connected devices. Cooling is done by free air convection, eliminating the need for additional fans – increasing the reliability of the device.
